The former Aston Villa marksman registered his eighth goal of the season on Saturday as Crystal Palace edged Watford 1-0 at the Selhurst Park.
The goal has made him go joint with Tony Yeboah who played in the Premier League in the 1990's with Leeds United on 24 goals as the greatest Ghanaian scorers in the Premier League history.
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."
