Ayew paid tribute to manager Roy Hodgson after his impressive winner.
"The most important thing is the teammates and the manager are giving me the freedom to play and to express myself and that's what is making me do all the things I'm doing today," he said.
"I thank the gaffer because the gaffer has faith in me and the staff and the club - [Steve] Parish and Dougie [Freedman] and Mark Bright so today is a good day for me and I just need to keep going and keep working hard.
"The most important thing for us is to keep winning games, to keep having a positive vibe at the Training Ground and in the dressing room. We have to keep going to make supporters happy."
