Chelsea boss Frank Lampard believes Mason Mount will be able to deal with the increased scrutiny after starting the season in fine form and earning an England call-up as a result.
The 20-year-old has scored twice for the Blues having started all three opening Premier League games.
Mount, who played under Lampard while on loan at Derby last year, has previously been included in senior England squads but is yet to make his debut.
“It’s a setback, of course. My focus is then to make sure he’s OK. He’s had four years of constant football at an incredibly high energy and output level.
“We have to get that right. It’s the right thing to do, we have a strong squad and the performance last week was very good. We have to be strong as a squad and hopefully we’ll show that.”
Pedro will also miss out after injuring his hamstring in the warm-up ahead of the 3-2 win at Norwich, while Callum Hudson-Odoi remains absent.
