Harry Redknapp reckons that Arsenal’s match against Manchester United on Sunday is our best chance to beat the Red Devils on their turf for a long time.

Old Trafford has been a huge stumbling block for us since… forever. Although we managed to beat United 3-0 when they visited the Emirates back in October, replicating that performance at the Theatre of Nightmares is another kettle of fish entirely.

Of course, we did beat them in the FA Cup last season, thanks to a late Danny Welbeck goal (wipes tear) but it remains to be seen if we can do it again in the Premier League.

Former Spurs boss Redknapp thinks that this is our best chance to do it but we have to wake up after our 2-0 loss to Barcelona on Tuesday.

“Arsenal will be hurting after losing to Barcelona but they must wake up and realise there has never been a better time to go to Manchester United than this weekend,” he said.

“United are without Wayne Rooney and have plenty of injuries.

“They are a very ordinary team these days. Okay, they beat Shrewsbury in the FA Cup on Monday night but a vintage United side would have beaten them 6-0.

“Louis van Gaal is getting all the grief but the players aren’t good enough.”

The match on Sunday is a good opportunity to bounce back, as our players so often like to say. If we’re going to continue to challenge for the title, we can’t accept anything but a win.
