Tottenham v Manchester United

Manchester United will be looking for revenge on Sunday against a Spurs side who ended a 23-year drought at Old Trafford by winning 3-2 there last September.

Sir Alex Ferguson’s side haven’t been beaten at White Hart Lane in 11 games – winning eight times – and were 3-1 winners the last time the sides met there.

Wayne Rooney and Ashley Young did the damage that day and Rooney returned from injury to score in the 1-0 midweek win over West Ham in the FA Cup.

The England international also missed a penalty – his 10th from 27 attempts in his time at United.

Rooney’s form has been patchy this season – niggling injuries haven’t helped – and he is having to adjust to living in the shadow of 17-goal Robin Van Persie.

United undoubtedly owe their position at top of the table to the Netherlands international frontman who is 4/1 (5.0) to open the scoring in Sunday’s live game and 10/11 (1.91) to score at anytime against Andre Villas-Boas’ side.

But for all their attacking flair - United’s defending is their Achilles heel - and they’ve already conceded an Aston Villa-like 29 goals in 22 games this season.

If Van Persie's goals were to dry up – or if he was to get injured – United’s leaky defence would come under the microscope.

Gareth Bale did a lot of damage with his surging runs at Old Trafford and scored in the 52nd-minute - and if he can stay on his feet long enough – could be a bit of value at 2/1 (3.0) to be an anytime goalscorer with Paddy Power.

Spurs were previously put up in this column as a bet to nothing to finish in the top four and 10/11 (1.91) to qualify for the Champions League play-off place despite being their own worst enemy at times.

Jermain Defoe scored a late consolation for the home side in the 3-1 defeat last season and is 6/1 (7.0) to get the game’s opener or 17/10 (2.70) to score at anytime while Clint Dempsey is 8/1 (9.0) to give Spurs the lead.

These two attack-minded sides have produced 15 goals in their last three league meeting at a repeat of last season’s 3-1 scoreline for United is 14/1 (15.0) or this season’s 3-2 win for Spurs is 20/1 (21.0).

For the neutrals a punt on more than 3.5 goals at 13/8 (2.63) with Paddy Power should keep them entertained.

Chelsea v Arsenal

In the earlier game on Super Sunday, Chelsea and Arsenal are in an altogether different space and both have underperformed massively this season.

Chelsea’s home record goes from bad to worse after they surrendered a 2-0 lead against Southampton on Wednesday night and have not won any of their last three home games in all competitions.

Arsenal have managed to steady the ship and squeezed through to the fourth round of the FA Cup with a 1-0 win over Swansea at the Emirates on Wednesday night, but sit eight points off their Sunday rivals.

The Gunners won their last league tie at Stamford Bridge -thanks to a Robin van Persie hat-trick - but Chelsea beat them 2-1 at the Emirates earlier this season.

Given Chelsea’s Stamford slump the Gunners at 2/1 (3.0) in Paddy Power’s draw-no-bet market looks a decent compromise wager.

The one positive for the Blues is that new signing Demba Ba scored on his debut against the Saints midweek.

If Demba Ba scores last in this game, Paddy Power will refund all losing First Goalscorer, Last Goalscorer, Correct Score & Scorecast singles on the match. (T&C’s apply)
