I reckon Rafa is more likely to rest him for Porto, if he's reasonably OK. He's never been too bothered about resting Gerrard in Euro games, much to the bafflement of Andy Townsend and Robbie Earle.
Putrerill celebrated a goal for the reserves recently by kissing an opposition player who had been giving him a hard time. On Brouwer I assume he thinks hes not that good.
