The Old Trafford legend isn’t happy with the Portuguese manager after hearing his complaints in the media this week.
Mourinho complained about his side’s fixture schedule after they beat Rostov 1-0 in the Europa League last night.
According to the United boss, his team would “probably lose” against Middlesbrough on Sunday as a result of having to play 11 matches in the last six weeks.
But Keane isn’t accepting any of that – and the ITV pundit chose to slam Mourinho while covering last night’s game between United and the Russian minnows.
As well as calling the comments “garbage”, Keane also asked if the job at Old Trafford is too big for Mourinho:

It’s hard to see how it would be too big for Mourinho considering his CV is littered with spells at top clubs, including Chelsea, Real Madrid and Inter Milan.
We now wait for the opinionated Portuguese manager’s response to Keane’s comments.
