The Portuguese attacker came off the bench to set up Jack Collison's winner.
"Since I have been injured I have not really had the chance to play much since I came back, but everything is in place. I'm working very hard to get my place back. My stats are still looking good, but obviously I'm still looking to improve on them. The priority on Saturday was getting the win, so that was the main thing," he told whufc.com.
