Meanwhile, Legit.ng previously had reported that Jose Mourinho has blamed Manchester United misfiring stars for the below-the-par display against Crystal Palace in Saturday's Premier League clash at Old Trafford again.
However, Mourinho may face more hurdle in the race to sign the 27-year-old Koulibaly, as Man United chiefs may turn down the massive fees for a player.
He didn't name names - but the decision to replace Pogba with Alexis Sanchez after 68 minutes was telling.
'My feeling is was not enough from the heart, we must play with brain, we must play with also heart and I think there was not enough heart, ' said Mourinho. "I think that's the word to describe it".
He said: "If we play with the same philosophy against Young boys then we don't win and have to go to Valencia and win there".
"They're inconsistent, not just in games, but from half to half within games", he said on his own podcast, per Sky Sports. "But we need to fight for this manager, the team and the club". "If you feel pressure to play matches at home where the people come to support, come on? When they are open, they change".
"We played a game like it was one more game and I don't think it was one more game".
"I would say if we have him for the Christmas period where we need, if possible, every player to be available for that hard period until the Newcastle match on January 2. Marcos Rojo has some little injury and Victor an injury - a proper injury - that will keep him out for a while, so Jones, (Chris) Smalling and Bailly are the three we have at the time". That peril should be avoided on Tuesday by United having switched pre-match bases to a hotel much closer to the ground.
"I kind of enjoyed it", Shaw said of Mourinho's rebukes. I think it is only a matter of time until they go in.
