Roy Keane and Jamie Carragher in disagreement over Man United’s Ralf Rangnick decision

Former Manchester United skipper Roy Keane has criticised the Red Devils’ decision to appoint an interim manager rather than a permanent successor to Ole Gunnar Solskjaer.

Ralf Rangnick is expected to be announced as United boss until the end of the season, when the Premier League giants will finally make a long-term appointment.

The German is renowned as one of the godfathers of modern coaching, having played a key influence on top managers such as Jurgen Klopp and Thomas Tuchel.

He will arrive at Old Trafford with a remit to turn around their form quickly, with United currently languishing in ninth following embarrassing defeats to Liverpool, Manchester City and Watford.

Solskjaer paid the price for those defeats and was sacked the morning after the 4-1 loss at the Hornets last Sunday.

United made it clear when they sacked the Norwegian that an interim appointment would be their preferred method of replacing him.

And that has led them to Rangnick, who has previously helped to turn RB Leipzig into powerhouses in the Bundesliga.

Keane though believes that it is the players who should hold the responsibility for recent results and questioned the decision to appoint Rangnick as an interim boss.

“First of all, it was disappointing for Ole to finish in such a low obviously going through a difficult time the Watford result was really poor and the performance,” he told Sky Sports.

“Obviously, I’ve argued with Jamie about a manager getting enough time and Ole did get enough time and the results and the performances over the last couple of months have been really poor.

“So, there was no real surprise after the Watford game but the club now have to regroup, get somebody in and get the deed over the line.

“I don’t think it’s ideal this interim stuff until the end of the season but it is what it is and they have to get on with it.

“But ultimately, when I look at the last few performances from the players, they’re nowhere near good enough for Man United but the manager paid the price.”

Liverpool icon Jamie Carragher disagreed with his fellow pundit though, insisting that the appointment of Rangnick is a positive step for the Red Devils.

“I think the appointment of who it looks like they’re going to bring in is a positive step in terms of how he wants the football played now the top teams all play that way,” he told Sky Sports.

“The way this guy wants his teams to play going back 20 years since he started coaching so I think it’s positive.

“Nobody has to play the same way but top level football is played like that. United were a million miles away from that.

“I think this guy is coming in, Ralf Rangnick will make sure United get in the Champions League next season.

“But the biggest job he has it to identify the next coach his role will be taking away from the people at the top and they will take advice from him. He will want the next coach to be in his mould.”
