Roy Keane is convinced Manchester United's players will let down manager Ole Gunnar Solskjaer.

The former United captain made the prediction ahead of the derby defeat to Manchester City.

"I don't fall for this carry on that there is going to be a brilliant reaction from these players," said Keane on Sky Sports. "These are the same players that threw (Jose) Mourinho under the bus and they will do exactly the same to Ole.

"Leopards do no change their spots. There are too many bluffers at this club to get United back to the very top.

"Even the point that we're talking about Man United trying to finish fourth tells you how the standards have dropped at United over the last few years both on and off the pitch. This is a big test for Ole."
