Last season's top scorer at Selhurst Park started last night for the opposition and was soon on the scoresheet sliding home after 14 mins.
The Finn, who received a mixed reception, refused to celebrate the goal.
It turned out to be the winner and leaves Palace just one point above the relegation places.
There's a chance this weekend with the FA Cup taking over.
Palace are looking to make it into the 6th round when they face Aston Villa at Selhurst Park on Sunday, ko 3:45pm. The match is live on ITV 1.
