Martin Keown has questioned the impact Ralf Rangnick has had since joining Manchester United.

Having been handed the interim manager job in November, Rangnick has struggled to turn the team’s situation around on the pitch and appears to have a strained relationship with technical director Darren Fletcher as he is unhappy that the former midfielder of United gives instructions to players from the bench.

With Erik ten Hag taking over from Rangnick this summer, Keown is unsure where the German fits into United’s future plans as a consultant, having apparently played a minimal role in appointing his successor in the dugout.

“Recruitment has to be linked to the new manager,” Keown told BT Sport.

“You look at Rangnick in all of this, I don’t think he was part of that job offer. He didn’t even speak to her [ten Hag].

‘Rangnick passed out a bit. He did not follow the company’s line of conduct. Some things I hear him say about Darren Fletcher, what does he do at the club?

“There doesn’t seem to be the kind of continuity that I would expect. So how do you do that overnight with a new manager walking through the door?”

Rio Ferdinand suggested Rangnick doesn’t take responsibility for United’s problems

Meanwhile, former United defender Rio Ferdinand has praised Rangnick for being brutally honest about his side’s current issues. Rangnick claimed earlier this week that the Red Devils may need to make as many as 10 signings this summer to significantly improve their squad.

Yet Ferdinand also feared the 63-year-old would try to shift the blame after a disappointing tenure.

Ferdinand added: “He played his part. On the one hand he was honest, which was refreshing to see.

“But on the same point, it goes to the point, does he relieve himself to have his fingerprints over such a period where the number of wins you expect from them has not materialized?”
