Ostersunds need 'miracle' to defeat Arsenal

Arsene Wenger's side put three past Ostersunds and kept a clean sheet in the first leg to emerge victorious. 

Ahead of the second leg, Potter said: "You need one of the biggest football miracles to go through, so we have nothing to lose."

"The only thing you have is the regret of not giving it everything. It is a wonderful opportunity for the players and myself to have this experience," the former York City man said. 

Ostersunds will be hoping they can channel their inner-Wigan Athletic after the championship side pulled off a shock defeat to knock Manchester City out of the FA Cup on Monday night. 

Arsenal, on the other hand, will be feeling their place in the last-16 is all but secure. Anything is possible, however.
