Tuchel’s comments come just a day after he said Hudson-Odoi needs to play hundreds of games at the “highest level” to complete his Chelsea turnaround.
“The only person who can decide this and answer this question is Callum,” Tuchel said on Friday.
“It’s as easy as that. Is there a turning point? OK, he needs to prove it. He needs to play the next 250 games on the highest level and then that was the turning point. But is it a turning point if he does a brilliant match tomorrow? No.
“It’s only a turning point if he makes it a turning point – and only if he does not only do one good match, one good half, 60 good minutes, but if he does it consistently,” Tuchel added. “It’s as easy as that with every player.”
