Chelsea manager Thomas Tuchel has held talks with Callum Hudson-Odoi after hauling him off after substituting him on against Southampton.

Tuchel on Saturday brought Hudson-Odoi on a half-time as Chelsea chased an equaliser at St Mary's, only to substitute the substitute 31 minutes later.

"It is not a big thing at all for me," Tuchel told the club's official website.

"I have spoken to Callum, and I've spoken to the whole group. Sometimes, these things happen in football and it was just my decision.

"Maybe I was being harsh on him because he was on my side of the pitch and I was up close to him, but I did not feel that he was really into the game.

"I didn't think he was totally sharp and that is why I took a hard decision on him. But that decision was in the moment and for that day only.

"For me, this is absolutely not a big thing and only becomes one if people want to talk about it."
