Manchester United hero Andrei Kanchelskis feels Andrey Arshavin has struggled at Arsenal because he's "physically weak".

Kanchelskis also branded the Russia captain as "average".

"Of course Arshavin is an average player, would you say he is a top footballer like Nasri or Fabregas? And his four goals at Anfield don't prove anything. I am convinced that the key quality for a big player is to play consistently not 45 or 60 minutes, but the whole game.

"He is physically weak, but he has some other qualities," the former Russia international told Sovetsky Sport.
