Chelsea's Sterling not ready to face Dortmund, says Potter

DORTMUND, Germany : Chelsea's Raheem Sterling is back in training but will not be ready for their Champions League last-16 first leg at Borussia Dortmund on Wednesday, coach Graham Potter said on Tuesday.

Sterling took a knock to his knee in training last week, making him the eighth Chelsea player to be sidelined with injury along with fellow forwards Christian Pulisic and Armando Broja and long-term absentees N'Golo Kante and Edouard Mendy.

"The other players coming back from injury, Raheem, Kante and Pulisic, they'll just be working their way back at Cobham, (Chelsea's training ground)" Potter told reporters on Tuesday.

He added that Wesley Fofana, Mateo Kovacic and Denis Zakaria were back after being out with injuries.

"The challenge for us is to build them up and to make sure they're right from a gametime perspective but it's good that Wesley, Mateo and Denis are with the group."

Potter, who has been criticised by some Chelsea fans since replacing Champions League-winner Thomas Tuchel last September, has struggled to find a way to incorporate the club's new signings with a host of players returning from injury.

Chelsea signed more than half a dozen players in the January transfer window, including British record capture Enzo Fernandez for more than $130 million, and Benoit Badiashile, Noni Madueke, Andrey Santos, David Fofana and Mykhailo Mudryk among others.

"We've got the squad that we have. It's a squad that we're really excited about but, at the same time, we know
