The former Red Devils midfielder has outlined what is currently wrong at his old side as they struggle to make the European spots.
After such a promising start to life in Manchester, Erik ten Hag has come under heavy criticism for the performances of his side so far this season.
Manchester United currently sit seventh in the Premier League table and despite drawing with a good Tottenham side, came out of the game receiving criticism.
Speaking on Sky Bet’s Stick to Football podcast, Keane stated that teams don’t fear United anymore.
‘They are stuck between a rock and a hard place because again, you are Manchester United, the onus is even when you’re at home, flex your muscles, and more importantly, put fear into opponents’ mindsets.
‘But teams are playing Manchester United now and there is no fear anymore. I think teams are going to Old Trafford now and enjoy it!’
