Chelsea manager Thomas Tuchel believes the more is to come from Ruben Loftus-Cheek.
The 25-year-old is fighting for his future at Chelsea after returning from a loan spell with Fulham.
Tuchel is a big fan of the English playmaker, but speaking after the 2-1 win over Arsenal, the German says he will continue to push Loftus-Cheek to his limits.
"I'm generally happy with him and that why he's been playing," said Tuchel after the game.
"He deserves to play at this point of the preparation but I believe he can do even more.
"He can show up more, he can show more physical capability, he can drive more with the ball. I'm never satisfied with him.
"I have the feeling that we need to push him to the absolute limit but it's too early to judge Ruben."
