It was noticeable Rooney did not join in the touchline celebrations for Robin van Persie's second, whilst he was nursing an injury as Danny Welbeck took the acclaim for his delicate injury-time effort.
But Moyes claimed there were no problems regarding Rooney's dedication, saying: "When you cross that white line it is very difficult not to be committed.
"Lots of people are judging you.
"When you cross that white line it is up to you. I thought he was incredibly committed for the team and helped set up two goals."
