Arsenal are set to make a move for Stuttgart defender Serdar Tasci as Arsene Wenger looks to strengthen his back four once again. Wenger is ready to splash the cash after forking out £10m to sign Thomas Vermaelen from Ajax last week and wants more reinforcements at the back.

Tasci, 22, is regarded as one of the best young defenders in Germany and has also been tracked by AC Milan and Juventus after he earned rave reviews last season which saw him force his way into the Germany side.

The Arsenal boss is believed to be a big fan of Tasci who can play in the centre of defence or at right back and the German admits he would relish the chance to play for a bigger club in Europe, saying: "I have the ambition to move clubs one day, but the time and circumstances have to be right for me.

Stuttgart are currently in talks with Tasci to extend his contract, but cannot agree a deal which leaves the door open for Arsenal to clinch his signature.
