Italian giants AC Milan are reportedly keeping close tabs on Werder Bremen defender Per Mertesacker.

The 25-year-old German is on the Rossoneri's radar as a replacement for their ageing backline.

The injury to veteran defender Alessandro Nesta has only heightened speculation that Milan will be looking to shore up their defences in the summer.

Thiago Silva is currently their only defender under the age of 30, and according to TMW - Mertesacker would be a useful addition to the squad.

A €10 million bid might be enough to bring him over to the San Siro although Milan could find it difficult if reports of Bayern Munich's interest in the same player turn out to be true.
