The striker has endured an injury-plagued campaign, but admits the goal will do wonders for his confidence.
“I am very happy," Milik, who for the second successive year has missed a large portion of the season with a knee injury, reflected following the final whistle.
“I went through six bad months with the injury, now I am ready to play and I am happy with his win.
“After my goal, we believed more. It really was a tough match."
