RVP questioned both David Moyes’ tactics and his team mates form to Dutch TV after United’s embarrassing defeat against Olympiacos in midweek, leaving their season hanging by a thread.
The Dutchman has had niggling injuries this season but hasn’t really found the form of last term where he was a major part of the Red Devils winning the league under Sir Alex Ferguson.
Yorke knows the pressure of leading the line at Old Trafford and he has urged van Persie to do his talking on the pitch rather than in interviews.
“When things are going right there’s all good stuff coming out of United, there’s no negatives,” Yorke said.
“Suddenly this year results haven’t been great, his performances haven’t been great, he hasn’t scored, certainly the number of goals when he came in, and it seems the impact has gone, not just from van Persie but throughout the team.
“So there are questions and players will have their say. But at the end of the day he’s playing for a football club like Manchester United and he’s got to be very aware of what he says.”
