"It was very important for us. West Ham were three points above us, and we needed to keep doing the right things we've been doing," said Cole, a former Hammer.
"It was a great win - it's always nice to come back to your old club. I've scored a few against West Ham but never celebrated - the most important thing was getting the win.
"It's a great group of young players here and we've got the right manager for them - they have done really well."
