Fiyako Tomori was delighted for Chelsea teammate Christian Pulisic after his hat-trick against Burnley on Saturday.

The American took advantage of his first Premier League start since August by netting the 'perfect' hat-trick at Turf Moor.

And Tomori says the performance was a result of Pulisic's tireless work in training.

"Everyone is disappointed when they don't play," Tomori told the Evening Standard. "We have got a lot of talented players, so you just have to be patient and when you get your chance you have just got to take it like he did on Saturday.

"I am really happy for him — that patience and hard work he showed in training has paid off. You have got to be on top of your game, not only in the games but in training as well.

"It is good Christian has come in because everyone has to be on their toes. No one knows their position is safe and that drives the team on and brings the best out of each individual."
