Cape Town - Former captain Roy Keane on Wednesday blasted Manchester United's current crop of players saying the club has "slackened off" on and off the pitch in recent years and have fallen behind their rivals.
Bernardo Silva and Leroy Sane struck for Manchester City in 12 second-half minutes at Old Trafford on Wednesday, to inflict a seventh defeat in nine games on United in a 2-0 loss.
United remain three points adrift of the top four and next face Chelsea in their top four fight to qualify for next year's Champions League.
Keane offered a brutal assessment of the players before the derby criticising the effort and desire of some players within the club.
"These are the same players that threw Mourinho under the bus and they'll do exactly the same to Ole," Keane said. "Leopards don't 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 chatting about Man United trying to finish fourth shows how the standards have changed both on and off the pitch."
Keane also gave his opinion on Paul Pogba after the Frenchman said his side had put in a "disrespectful" performance against Everton and needed to adjust their attitude.
"The number of times we've seen him in games where he is not sprinting or running back. He's a big problem for United. He mentioned body language and pride, but I don't see it in his performances. My eyes don't lie to me.
