Werder Bremen defender Per Mertesacker is in the sights of Tottenham.

The Germany international has been a long-term target for Arsenal and was tipped to move to North London last month.

Redknapp could be forced into buying more than one new centre-half in the summer with concerns also persisting over the fitness of Ledley King.
