"But also, Chelsea can win because they can see how their players are getting on", he explained. It looks like they're in good hands.
Tomori and Mason Mount were granted special dispensation to feature against their parent club, yet the Rams might have wished that was not the case when Davide Zappacosta's cross struck the former's standing leg and diverted in for the fifth-minute opener. However, he could have given the Rams the lead minutes earlier after being released through on goal but he hit his effort straight at Willy Caballero. "Derby were excellent.

"I sort of slipped out the back door when I left".
It will be the Blues' third match in the space of six days, having beaten BATE Borisov and Burnley in the Europa League and Premier League respectively.

Key Stat: Chelsea (31) and Derby (30) have combined to score 61 goals in all competitions this season.
Cahill's future at Chelsea is being called into question and he certainly didn't perform with the consistency of old during the Derby game. "He just said he's so proud of all of us, to come here and play the way we played, and we can leave here with our heads held high".
