Cape Town - Per Mertesacker says controlling the midfield will be vital to Arsenal’s chances at Manchester United on Sunday.
The Gunners have already won at Old Trafford this season, when Danny Welbeck's goal settled a pulsating FA Cup quarter-final tie against his former club.
Mertesacker is confident that Arsenal can produce a similar performance this weekend as they look to bounce back from Monday night’s defeat to Swansea.
