He has come under heavy criticism after string of disappointing performances and fans have grown infuriated with his showings.
Rooney has started all of Man United’s Premier League games so far this season, but after playing the full 90 minutes in Wednesday’s 3-1 EFL Cup victory at Northampton, many believe he may be left out of the Leicester fixture at Old Trafford.
Speaking about the Englishman, Parlour claims Mourinho will need to figure out what to do with him.
“I think Rooney is the big problem at the moment,” he said.
“What does he [Mourinho] do with Wayne Rooney? Does he play him or not?
“I have got a funny feeling this might be the time that Rooney is left out, just to recharge his batteries and get him out of the focus a little bit, because he is the man at the moment who is getting the most criticism.
“I don’t know if he [Rooney] is enjoying his football at the moment. Everybody goes through it, and sometimes you do need to be pulled out of the firing line.
“I am sure that Wayne Rooney, with his quality, will be able to handle that.”
Mourinho hasn’t been shy to drop big players at his former clubs Real Madrid and Chelsea, but he has failed to leave the Englishman out yet.
With Rooney playing against Northampton, hopes are the Portuguese boss is able to experiment with the No.10 role for what suits the team best.
After being dropped for a few games, Rooney could even feel the competition for his spot on the side and start performing, rather than producing uninspired performances and continuously slowing down United.
