WEST HAM are rumoured to be lining up a bid for Rosenborg defender Michael Lustig, according to media in Norway.

Fotbollexpressen.se claim a number of European clubs are interested in the young Swede, with Rosenborg's sporting director Erik Hoftun admitting it would be difficult to hang on the player if the Hammers come calling.

“We will of course keep him, but when the big clubs start to let hear from them, it can be difficult,” he said.

Lustig is currently on duty for Sweden in the European Under-21 Championships.
