Thomas Tuchel’s message for out-of-favour Callum Hudson-Odoi.
The England international has not started any of Chelsea’s last eight matches after initially enjoying a regular place in the first team under Tuchel.
Tuchel has asked the 20-year old to push himself harder to make it to the first team.
Hudson-Odoi has scored five goals and made three assists in all competitions for the Blues this season.
Tuchel said: “Callum needs to understand how to use his potential.
“He needs to understand how to push himself to the absolute limit, and not be happy with 80, 85, 90, 95 per cent. He simply cannot be happy with that in any single day.
“He needs to learn and understand that and live up to that. Once he does this, he will make his way and leave his footprints.”
Tuchel continued: “We are very happy with Callum since we arrived here. Everything that counts is what he does here, and how he lives up to his talent that he clearly has.
“He has big talent, and with that big responsibility. This is what he is trying, sometimes better, sometimes okay, sometimes very good, and when we have a chance we let him play.
“But please don’t forget we only have three changes here in England, which is a big disadvantage, also for guys like Callum, like Tammy.
“We cannot give them 20 minutes here, and 20 minutes there, which could make a huge difference for their feeling, but also for their development.
