Inter Milan chief Marco Tronchetti Provera has left the door open to a sensational return for Samuel Eto'o. Tronchetti Provera is aware of the speculation and believes Eto'o is already growing tired of life at Anzhi - despite the massive money he's on.

The Pirelli boss declared: "Eto'o is a great champion. He's still very good.

"He had a good offer ... but he's a player used to great challenges. And this is something he is now missing."
