Roy Keane has said Jose Mourinho is "back to his old cocky self" now that Manchester United are regularly winning games, but he would like to see him to show "a bit more humility."

United have won five games in a row in all competitions and are chasing silverware on three fronts -- the EFL Cup, the FA Cup and the Europa League. They remain sixth in the Premier League but have closed the gap on fourth place to two points putting them in contention for Champions League qualification too.

When asked if Mourinho had his swagger back, Keane told ITV Sport: "Yeah, which is a bit of a shame really as you'd like to see a guy with a bit more humility.

"But you knew once they started winning a few games he'd get back to his old cocky self."

Former United captain Keane also lauded the recent form of Atletico Madrid striker Antoine Griezmann and said he would be an excellent signing for Mourinho.

"He's been fantastic," Keane added. "I've been really shocked at the level he has been playing at over the last two or three years.

"He's been fantastic and we're seeing the goals now, on a regular basis in all the big games -- at international level and on the big Champions League nights.

"He's a really top player and obviously he's been linked with United. What a player he'd be for United."
