The Dutchman won and converted a second half penalty to net his first Reds goal since February before joining Sir Alex Ferguson, his staff and the substitutes on the visitors' bench at the Britannia Stadium.
"I had to score that one and thankfully it went in, and after that the relief of a couple of weeks came out, I would say," the Dutchman told MUTV. "I wanted to celebrate with everyone; with the players, the staff, with all the players involved even on the bench because they've been great to me from day one.
"Even when sometimes it is a little bit harder, they still believe in me and they still support me and help me wherever they can. That's why I wanted to join everyone."
