Champions League Special: Manchester United Pen Pics profiles the key members of Manchester United's squad ahead of their monumental clash with Barcelona in Rome...
Can Manchester United do a double-double? Sir Alex Ferguson will hope that his starting XI have enough in the tank to do so as they meet Barcelona in the Champions League final on Wednesday evening.

The Old Trafford side have already lifted the Premier League title, so takes a look at each of the players that are in line to feature in the European showpiece encounter on Wednesday.

Edwin van der Sar
The indefatigable Dutchman is still going strong at the age of 38 and will start between the posts for United. Van der Sar was one of the key players in last year's final and also won the tournament all the way back in 1995 with his boyhood club, Ajax. This could well be his last ever major final, although he's under contract for another season.

John O'Shea
O'Shea has been given a real European baptism of fire this season: largely restricted to rotational appearances prior to this year, the Irishman has stepped up to the challenge of being first-choice right-back. He has even managed to chip in with a vital goal - a starting spot in the final is ample reward.

Rio Ferdinand
England international Ferdinand is considered one half of what is perhaps the world's best central defence pairing. The 30-year-old Londoner was the captain of last year's victorious side and can be counted on for both experience and aerial prowess.

Nemanja Vidic
The remaining 50 per cent of that dynamic duo, Serb ace Vidic is a threat at both ends of the pitch, being both an accomplished stopper and an excellent attacking header of the ball.

Patrice Evra
The Frenchman is considered by some to be the world's finest left-back, and certainly he's won the trust of coach Sir Alex Ferguson as he's started 11 of his side's 12 European encounters this season. He played in last year's final, as well as in Monaco's 2004 final defeat to Porto.

Ji Sung Park
The South Korean international is arguably the most famous Asian footballer in the world at the moment, and Sir Alex Ferguson often includes the 28-year-old in vital matches. He netted the crucial opening goal against Arsenal in the semi-final and is renowned for his incredible energy levels.

The 21-year old joined the club in 2007 from Portuguese champions Porto and his lung-bursting runs from central midfield have became his most notable characteristic. The young Brazilian is a full international and is expected to line up against Barcelona on Wednesday.

Michael Carrick
Often described as the unsung hero of the Red Devils' midfield, Carrick has came to the fore this season as one of the most influential playmakers in the English Premier League. The former Tottenham Hotspur man has a wide range of passing in his locker and perfectly complements the dynamism of the likes of Darren Fletcher and Anderson.

Ryan Giggs
The PFA Players' Player of the Year remains a hugely gifted footballer, and has lost none of his creativity or guile despite being 35 years of age. The veteran already has two Champions League medals in his cabinet, and will be desperate to cap a sensational season with victory in Rome.

Cristiano Ronaldo
The Ballon d'Or winner hasn't quite been as prolific this season, but his stunning goals against Porto and Arsenal in previous rounds have further confirmed his big-game mentality. The Portuguese will relish the opportunity to showcase his talents once again in the biggest match of them all.

Wayne Rooney
Rooney has came of age this season, sacrificing goals for the success of the team when operating in a left-wing role. His backtracking, tireless working and his lethal finishing make him a real threat, and the 23-year-old has four goals and three assists in this season's Champions League.

Tomasz Kuszczak
Kuszczak has been forced to share goalkeeping duties with Ben Foster and of course the impenetrable Edwin van der Sar, which has limited his first-team opportunities to just seven starts this season. The Pole will be battling with Foster for the number one jersey when Dutchman van der Sar inevitably retires.

Jonny Evans
The Northern Irish international has been an able deputy when either Vidic or Ferdinand have missed out, and has produced some inspiring performances in big matches both domestically and in Europe. Evans is still only 21, but has shown maturity and is highly-rated by Sir Alex Ferguson.

Rafael Da Silva
The more prominent of the Brazilian brothers, Rafael has had a run in the first team due to injuries to Gary Neville and Wes Brown and has been hugely impressive both defensively and through his marauding forward runs. The 18-year-old has made a push to be considered first-choice full-back for next season.

Paul Scholes
One of the greatest passers England has ever produced, The central midfielder may be in the twilight of his career, but is still capable of a piece of brilliance, as Barcelona found to their cost in the Champions League semi-final from last season.

Nani has been on the periphery of the first-team this season due to some inconsistent displays, but the 22-year-old still has the ability to turn full-backs inside out, and packs a lethal shot when given the opportunity.

Darron Gibson
Gibson is a player in the mould of Michael Carrick, rarely surrendering possession and performing as the midfield lynchpin. The 21-year-old has recently made his Republic of Ireland debut, and will hope to make more of an impact on the first-team next season.

Carlos Tevez
The Argentine's future is still up in the air, with a move away from Old Trafford looking like a possibility, but there can be no doubting the passion he shows in every match. The former West Ham striker also has a knack of scoring vital goals in big matches.

Dimitar Berbatov
At £30.75 million, much has been made of the Bulgarian's exorbitant fee, and sections of the Manchester United support continue to question his work ethic and his involvement in matches. However, his deft touch and superior footballing brain make him a prized asset for any side.
