Fabian Schar – FC Basel
The Swiss youngster has caught the eye this season with a series of sturdy, mature displays in the Champions League, and is not expected to be at the club beyond the summer. Arsenal could be all set to lose Thomas Vermaelen this summer as he seeks more game time, and in his absence Wenger will need defensive cover. Young enough to grow into an important player, but still enough of a rookie to act as adequate back up to the established pair of Mertesacker and Koscielny.
