German legend Lothar Matthaus has some concerns over new Bayern Munich signing James Rodriguez.

Matthaus believes the former Real Madrid attacker "will do well", but can also see difficulties in the future.

He told Kicker: "He's a goal-scoring player, he's a scorer in the past World Cup in which he scored 6 goals for Colombia.

"He's not very fast but he'll do well with Bayern."

Matthaus, however, added: "Playing in the middle, that is the position of Thomas Müller, it will be interesting to see how (coach) Carlo Ancelotti resolves the situation."
