Chelsea defender Fiyako Tomori says Mohamed Salah and Roberto Firmino are the toughest strikers he's faced in the Premier League.

The 22-year-old has stepped up into the top-flight this season after a loan spell with Derby County in the 2019/20 campaign.

"It has been different for me this season, just because it is the Premier League and it is a step up. You have to be more focused and prepared, always alert," the 22-year-old told Sky Sports.

"In the Championship you have a lot of different strikers - some love it in the air or like to go in behind. But then I'm playing against [Roberto] Firmino and he's dropping deep into midfield. Things happen a lot faster and mistakes are punished more harshly.

"Firmino was probably the most difficult [to play against] - along with Salah. Every time they got the ball, I was thinking, 'This is a challenge but this is where I want to be - this is a chance to prove that I can play at this level.'"
