Arsenal boss Arsene Wenger admits he's eyeing potential transfer targets - but not just what they do on the ball. Wenger's goalkeeper ­Wojciech Sczcesny was with Poland, Van ­Persie with Holland, Tomas Rosicky with the Czech Republic and he still has Theo Walcott and Alex Oxlade-Chamberlain with England.

Wenger said: "The mental aspect within a squad is so much more ­important these days. It has become one of the most essential things in the modern game.

"It is the magic or the mystery of a team. Is it a good team, half a team or no team at all? I can see here which players are contributing to the team spirit and which players destroy the team."
