Stuttgart defender Serdan Tasci is in the sights of Arsenal boss Arsene Wenger.

Wenger, after clinching a deal for Lorient stopper Laurent Koscielny, still wants another centre-half signing before the season starts next month.

Tasci, rated at £11 million by Stuttgart, is under consideration. Wenger is also keen on his teammate, midfielder Sami Khedira.

Defender Tasci is contracted to Stuttgart until 2013.
