Jack Collison says West Ham United teammate Valon Behrami will come back stronger from his knee injury.

Collison did his knee rehab with the Switzerland international and told whufc.com: "Obviously every time you get injured it's not a nice feeling and unfortunately for Valon he's going to be out for a little bit longer.

"He's a good character and I'm sure he's going to come back strong, as I'm planning to within the next few weeks."
