Roy Keane has disagreed with Cristiano Ronaldo over the level Manchester United should be competing at.
Ronaldo recently stated that the minimum expected of the Red Devils should be a top-three finish in the Premier League, but Keane is of an even more ambitious opinion.
Shortly before United's 2-2 draw at Aston Villa on Saturday, the legendary ex-captain told Sky Sports : "I disagree with that.
"If you're playing for Man United your mindset should be that you're at the very, very top. We have had this conversation many times before and they should at No.1.
"But where they they are at the moment, the reality is, they are up against it. Their performances haven't been great, some of the results particularly."

In a controversial interview earlier this week, Ronaldo - who missed the trip to Villa Park through injury - stated: "Manchester United should win the league or be second or third.
"I don't see other positions for Manchester United to be honest, I don't see. In my eyes, I don't accept that our mentality be less than to be in the top-three.
"We are capable to change things now. I don't know the specific way; I'm a player, not the coach, the president. I know the way but I'm not going to mention it here.
"What I can say and something I can say we are in control, we can do it better, all of us. Manchester belongs in important things, we have to change that."
Keane and Ronaldo's former teammate, Wayne Rooney, also disagreed with the five-time Ballon d'Or winner and said: "Manchester United have to be a top one team, not top three, and I think that’s the demands the fans put on you, the demands that club has.
"Of course they’re going through a very difficult period at the minute, but make no mistake that’s a club that has to be winning championships.
"It has to be winning trophies, and that’s the pressure we come in with playing or working at Manchester United. That’s where they need to get back to. I’m sure they’re trying to do the right things to get them back to that place."
