Brendan Rodgers said that he wasn't in the right frame of mind to play for the Foxes in the loss to the Saints.
According to reports, the 21-year-old French defender, who signed a new deal with the club in March, wants to join the Blues.
His team lost their second game in a row.
Rodgers said that the young player is not in the right frame of mind.
A lot is going on behind the scenes. It's a tough time for him. He is a good person. While he's been here, he's been 888-609- 888-609- 888-609-
He missed most of last season with a broken leg, but has played 52 games for the club since joining in 2020.
The 25-year-old Youri Tielemans started on the bench for the Foxes but was introduced in the second half.
"If your mind isn't quite on playing, this is a level where you have to be completely concentrated and focused - and if you're not, unfortunately you can't play," Rodgers said.
There have been a few offers for some players, but the club wouldn't want to sell them.
I know how the game works and that's why they're not for sale. I don't know what will happen over the next few weeks.
