The Gunners captain is the subject of a bid from Louis van Gaal's side but Arsene Wenger is stalling the move until he can find a replacement for the Belgian defender.Arsenal captain Thomas Vermaelen is unsure whether he will stay or go this summer.
The central defender wants a new club after falling behind Per Mertesacker and Laurent Koscielny in the pecking order at the Emirates Stadium, but Arsene Wenger is stalling his move to Manchester United while he lines up a replacement.

The Red Devils are willing to pay more than 8 million pounds for the Belgium international, who has left Brazil after his country's World Cup campaign ended at the quarterfinal stage.
Vermaelen is now ready to focus on his club future but, ahead of discussions with Arsenal, does not know where his future lies.
"I really do not know where I will play, Arsenal or elsewhere next season," he told the London Evening Standard.
"All my attention went to the World Cup. I will see when I talk with Arsenal."
Vermaelen has a year left on his contract with Arsenal but played just 14 league matches last season as the Gunners finished fourth in the Premier League and won the FA Cup.
