“I think Mkhitaryan is the long-term replacement for Wayne Rooney”
Ian Wright on Man United
United have been in fine form recently and are unbeaten in their last 11 games in all competitions.
And Wright reckons Mourinho’s men will be challenging for the title come the end of the season.
“United didn’t start off brilliantly and they’ve been trying to get themselves going,” Wright told BBC Radio Five Live.
“Mourinho was working out his best team and who was going to play where.
“He’s got something with Rojo and Jones at the back.
“Pogba is playing brilliantly.
“I think Mkhitaryan is the long-term replacement for Wayne Rooney.
“You know that with the quality of players they have, now they’ve got it going, you have to say Man United will be in and around it [at the end of the season].”
