Erik ten Hag will be having sleepless nights after watching the Manchester United team, according to Roy Keane.
The injury hit Red Devils were lacklustre in their 1-1 draw with Chelsea and were perhaps fortunate to escape with a point.
Cristiano Ronaldo continues to prove just how vital he is to United as he netted once again, scoring eight of the club’s previous nine goals.
Ten Hag will likely be under no illusions at the momentous task he has on his hands when he joins from Ajax in the summer.
United legend Keane, who won seven Premier League titles with the club, outlined the problems the Dutchman will have and commented on what Ten Hag’s arrival could mean for Ronaldo.
Keane told Sky Sports: “Ten Hag would have been watching the game tonight and he’ll be having sleepless nights watching the team.
“If you’ve got a player in your group who can score that amount of goals, they have to be involved.
“Ronaldo will want to play week in, week out. That’ll be the problem for the new manager, he’ll be looking for another striker, but Ronaldo won’t be hanging around if he’s not playing week in, week out.
“He won’t mind being rested for the odd League Cup game or European game if they’ve already gone through.
“I think he wants to play week in, week out and that’ll be a problem for the manager. He’ll be saying ‘I’ll have to rotate you in certain games’.
Keane also sarcastically quipped: “He’s [Ronaldo] such a big problem for Manchester United. Scoring goals week in, week out. It’s not good.”
The Irishman also indicated that there was no one area that needed overhaul, everywhere was in need of attention.
“Everything [needs a rebuild],” he said. “Don’t get me started on the midfield. Defensively… I’m still not happy with the goalkeeper. Couple of players up front… huge.”
Ralf Rangnick has been in interim charge since Ole Gunnar Solskjaer was sacked in November.
They were seventh when the Norwegian was axed and 12 points off then leaders Chelsea.
The Red Devils are currently sixth, but will drop back down to seventh if West Ham win their game in hand.
United are also a massive 25 points off league leaders Man City, having played two games more.
“They wouldn’t have done any worse if Ole was here, but obviously the decision was made and you can’t keep looking back,” Keane added.
“Go back as far as David Moyes, I’d always argue managers should be given more time than what they have. The reality of top football is there is no patience.
When asked if United would be in a better position had Solskajer stayed, Keane added: “If Ole had stayed on, in terms of their league position, I’d say yeah. You have to remember the last couple of games for Ole, you are talking about leopards and spots, the Watford game they never ran.
“They stopped running for Ole towards the end. There was the Liverpool game and they can rip anyone to shreds, but they kind of gave up for Ole at the end.
“I’m not saying it wasn’t right for Ole to go.”
