Manchester United striker Robin van Persie is reportedly unhappy at the club as he is still yet to be convinced by manager David Moyes.
The former Everton boss replaced the retiring Sir Alex Ferguson in the summer, with the latter's presence at Old Trafford thought to be one of the main factors that resulted in the Dutchman's move to the Premier League champions.
The ex-Arsenal captain cut a frustrated figure during the Red Devils' 1-0 defeat at Liverpool on Sunday, and his friends have allegedly revealed that he is yet to be won over by Moyes.
"Robin isn't happy and when that's the case he can't hide it on the pitch," a friend of Van Persie told the Daily Star.
"When he's frustrated he is capable of doing something silly, and you could see that against Liverpool.
"He feels it isn't the same with the new manager as he misses working with Fergie, who he really loved playing under. Some of Moyes' training methods are not to his liking either."
Van Persie has finished as the league's top scorer for the past two seasons.
