The pundit believes his former team have turned a corner under the Portuguese, but still feels they will struggle to mount a serious title challenge

The Old Trafford side have endured a testing start to the season under the Portuguese, losing two of four matches in the Premier League amid reported unrest within the club.
An alleged breakdown in the relationship between Mourinho and Paul Pogba has been the topic of much debate, while the manager is also said to be at odds with executive vice-chairman Ed Woodward over transfers.
