Manchester United great Paul Scholes slammed caretaker manager Ralf Rangnick after their Champions League elimination by Atletico Madrid.
Scholes did not hold back when criticising Rangnick's appointment and admitting that more "pain" is to come.
Speaking on BT Sport, he said: "How (Ralf Rangnick) was chosen to be manager of this club, I don't know. Getting a proper coach for this team is a massive thing.
"There is some real talent in this squad.
"The very first thing this club needs to do to get anywhere near winning the league again is getting in a proper coach who works for this team.
"If Diego Simeone was managing them, United would have gone through."
He then went on to add: "We have had a lot of pain and I think there is more to come until we get back to where we want to be."
