It's a landmark he is proud of but he was keen to reiterate that team achievements come before personal ones.
"I'm very pleased to have 50 goals but the most important thing is I have won two league titles in three years and played in the Champions League final. Like I always say the most important thing is the team and to help the team win trophies," he told MUTV.
"It's the first time in my career that I've been involved in a game with 10 goals! It was a crazy match and also a bit frustrating because we wanted to win it. I think we thought we had it won which was a mistake because we relaxed a little bit and West Brom made very good substitutions which helped their team. It's frustrating but the most important thing is we have won the league."
