Now the January window has passed us by, Premier League clubs have the chance to immediately assess their activity, or lack of, in the transfer market as they embark on the final third of the season.
QPR were the most active in the market last month as they brought in five players to aid their Premier League survival bid. Everton strengthened their attack by recruiting Nikica Jelavic, Newcastle United did likewise with the signing of Papiss Demba Cisse, while Manchester City added to their wealth of talent in midfield with the acquisition of David Pizarro.
Goal.com looks at those who are primed to make their debuts over the weekend and who they'll need to displace in order to feature for their new club.
|RYO MIYAICHI | BOLTON
Following in the footsteps of Jack Wilshere, the Japanese winger secured a loan move to Bolton on deadline day as he looks to gain regular first-team experience in the hope of cementing a place at Arsenal next season.
Although Bolton are hanging two points above the relegation zone, the form of Chris Eagles and Martin Petrov on the flanks has been one of Bolton's brightest points this season, which means Miyaichi will have to immediately impress Owen Coyle in order to feature against Norwich City this Saturday.
|MARVIN SORDELL | BOLTON
The forward was reportedly the subject of a bidding war between Cardiff City and Bolton before ending up at the Reebok on deadline day.
Sordell should be a welcome addition to Coyle's side who are struggling for goals this season.
In recent weeks, David Ngog has been the preferred choice in attack as both Kevin Davies and Ivan Klasnic have been restricted to appearances from the bench.
Despite Coyle's preference for Ngog, the Frenchman has two Premier League goals to his name this term and could be replaced by Sordell, who netted 10 in the Championship prior to his switch, for the match against Norwich City.
|NIKICA JELAVIC | EVERTON
The Croatia international arrives at Goodison Park with a blistering scoring record after netting 36 times in 55 appearances during his time at Rangers.
Jelavic should be a boost for David Moyes' side who have struggled in front of goal in the league this season, only Wigan have scored fewer so far, and it is Roberto Martinez's side who the 26-year-old could make his debut against this Saturday.
With Louis Saha sold to Tottenham on deadline day, Jelavic appears to be the natural replacement in Everton's attack.
|STEVEN PIENAAR | EVERTON
Pienaar admits he needs to regain trust from the Everton faithful after leaving Goodison Park just over a year ago for Tottenham.
The South Africa international struggled to impose himself during his time at White Hart Lane, and while injuries played their part, the midfielder had recovered from a groin problem by the start of November but has managed just 24 minutes over three appearances since then.
The form of Landon Donovan makes it unlikely for the 29-year-old to return to Everton's right flank, so for a starting place against Wigan, Pienaar would have to get in ahead of fellow loanee Royston Drenthe.
|PAVEL POGREBNYAK | FULHAM
Martin Jol has tipped the Russia international to fill the gap left by Bobby Zamora, who departed for QPR on deadline day.
It appears, however, that Pogrebnyak may not be an instant hit as he arrives at Craven Cottage having scored just one goal in the Bundesliga this season. In addition, the 28-year-old wasn't even the German side's first-choice striker, restricted to 14 appearances as Cacau was preferred to lead the line.
His chances at Fulham under Jol could be more forthcoming. The in-form Clint Dempsey has been playing in a forward's role in recent weeks and the USA international could drop back into midfield while Pogrebnyak partners Bryan Ruiz against Manchester City on Saturday.
|BOBBY ZAMORA | QPR
At 31, you could forgive Zamora's decision to pursue a move to QPR as he eyes a place in England's Euro 2012 squad this summer.
But for that he'll need regular football, and with Mark Hughes boasting seven strikers to choose from as QPR embark on the task of securing their Premier League survival, Zamora will need to have an instant impact at Loftus Road.
Replicating the debut of Djibril Cisse wouldn't be a bad start. The Frenchman arrived from Lazio and netted early on against Aston Villa in their 2-2 draw on Wednesday evening, and the prospect of he and Zamora in attack is likely to fill Hughes with confidence as his side host a leaky Wolves this Saturday.
|DAVID PIZARRO | MANCHESTER CITY
In contrast to January 2011 where Roberto Mancini splashed out £27 million on Edin Dzeko, the Italian's subdued transfer activity last month led to the sole signing of Pizarro on loan from Roma.
A player in the mould of Xavi, the 32-year-old arrives at Eastlands after being frozen out under Luis Enrique. But Pizarro, who played under Mancini at Inter, still has much to offer in Manchester City's pursuit of the Premier League title.
Sharp and composed on the ball, the deep-lying midfielder's effective distribution both long and short has been an integral part of his game during his time in Serie A. While Yaya Toure remains away at the Africa Cup of Nations, Pizarro has his chance to seize his opportunity against Fulham this Saturday as Mancini continues to overlook Nigel de Jong in City's midfield, while the Chilean offers more technically than Gareth Barry.
|PAPISS DEMBA CISSE | NEWCASTLE UNITED
Last season, Cisse ended the campaign as the Bundesliga's second-highest scorer behind Bayern Munich's Mario Gomez with 22 goals in 32 appearances. So there's reason for excitement at Newcastle United ahead of their match against Aston Villa on Sunday.
With the form of Demba Ba, who already has 15 league goals to his name this term, Cisse's prowess in the box should mean that he can forge an effective partnership under Alan Pardew.
The duo have just returned from a disappointing Africa Cup of Nations campaign where Senegal finished bottom of their group, losing all three matches. Although neither scored in the tournament, the pair never played more than 60 minutes together in a single game, with Cisse starting just once.
|SOTIRIOS KYRGIAKOS | SUNDERLAND
With Wes Brown ruled out until March, the former Liverpool man, who has arrived from Wolfsburg on loan, could be required sooner, rather than later.
Martin O'Neill has helped guide Sunderland to eighth since his appointment in December and with three clean sheets and just two goals conceded in 2012, the acquisition of the 32-year-old provides the defensive presence and experience required to help prolong that record.
His aerial ability could also be of immediate use as Sunderland face a trip to Stoke City on Saturday.
|SEBASTIEN BASSONG | WOLVES
The 25-year-old sealed his loan switch to Molineux on deadline day after finding his first-team chances limited at Tottenham.
The defender has started just one league game this term and played only 22 minutes of football in 2012 after coming on as a substitute during Tottenham's 1-0 victory over West Brom in January.
Bassong enters a Wolves side who sit second from bottom in the Premier League, and are without a league win in nine outings.
The centre-back pairing of Roger Johnson and Christophe Berra have been far from convincing as Wolves have shipped 43 goals this term and Mick McCarthy could be tempted to slot the Cameroon international straight into his side's defence as they face a trip to QPR this Saturday.
