Chelsea manager Thomas Tuchel has said he subbed off Callum Hudson-Odoi just 31 minutes after the winger came on in the 1-1 draw at Southampton because he was not happy with his attitude.
Hudson-Odoi came on for Tammy Abraham at half-time when the Blues were 1-0 down.
Nevertheless, after Mason Mount equalised from the penalty spot, Tuchel did not think the 20-year-old Englishman was offering enough as they chased a winner.
“Maybe it is even unfair, but it was my feeling,” Tuchel said.
Talking to BT Sport, he added: “I was not happy with his attitude, energy and counter-pressing.
“I took him off and we demand 100%, I feel he is not in the right shape to help us. It was a hard decision but tomorrow it is forgotten and he has all possibilities to start against Atletico Madrid [in the Champions League on Tuesday].”
