Roy Keane's warning for Erik ten Hag as he uses one word to sum up Man United's season

United enjoyed a comfortable win against Bees in their final home match of a miserable season as Old Trafford bid farewell to Ralf Rangnick and some players amid more protests against the Glazer family.

Monday marked a year since the postponement of the Red Devils’ home clash against Liverpool, when fans made their anger at the ownership clear in the wake of the European Super League debacle.

Supporters have protested at each of United’s final three home games and the anti-Glazer sentiment was clear before and during the victory against Brentford at Old Trafford.

This was the first match that Thomas Frank’s Bees had lost with Christian Eriksen in the starting line-up and there were times before and after Bruno Fernandes’ early opener that the Dane threatened to unlock the hosts.

A narrow offside decision denied Cristiano Ronaldo before half-time, but the veteran would get on the scoresheet after converting the spot-kick foolishly given away by Rico Henry.

Raphael Varane hooked home a deflected third as fans gave standing ovations to departing Nemanja Matic and Juan Mata as they were substituted on their final Old Trafford appearances.

Erik ten Hag will be in charge when United next play a home game in the Premier League and former United captain Keane sounded a warning for the Dutchman.

"It’s been a disastrous season on a number of fronts," Keane told Sky Sports.

"Off-the-field, obviously, change of manager, bringing a manager in and giving him a caretaker role that was never going to work.

"They're too easy to play against, not won enough games. A lot of players leaving the club and a lot of players wanting to leave the club. It’s been a long old season for them and they'll be glad to see the back of it.

"We know it’s a long way back, but of course, there is a way back. It’s the points total that worries me, to be so far behind. It’s such a gap. Big problem for Man United, whatever issues they’ve got, then you look at Man City and Liverpool.

"The last few years haven’t been good enough. The biggest worrying thing for me is the reaction. Not enough characters in that dressing room.

"If you haven't got a decent dressing room, you’re in trouble anywhere. I go back, decent personalities, characters. It’s a bad reflection of senior players at the club. A bad dressing room, forget about it, you’ve got no chance."

Keane also backed Ronaldo to remain at United next season, despite rumours linking the Portuguese superstar with a move this summer.

"I know there’s speculation but I can’t imagine Ronaldo not being at Man United next year unless something drastic changes in the summer," he added.

"If you look at the goals he’s got, he’s a threat and any manager would want to work with him. Simple as that."
