Belgium international Courtois, 26, has yet to return to training and is linked with a move to Real Madrid.
Should the deal for Kepa go through, it would be a club record purchase for the London club, surpassing the £58m they paid Real for Spanish striker Alvaro Morata last summer.

Was it ever in doubt? Hazard finds that well-worn side-netting in the left-hand corner. Game over. Chelsea win!

Yes Rob Green. He shimmies one way and the dives the other to push the ball away, which is placed at a nice height.

Perfect record from both teams. Another well-placed spot-kick. We're effectively into sudden death.

This could go on all night. No mistake as the ball is rolled into the bottom left corner.

In off the left-hand post. Even if Lyon's keeper had gone the right way he wouldn't have saved it.

Confident stuff. Marcelo goes one way, Green the other.

Calm as you like. A hop, skip and a coolly slotted kick put away as the keeper dives the wrong way.
SCORES! - Chelsea 0-1 Lyon
Jordan Ferri
Lovely penalty. Right into the side-netting and past Green, who dives the right way.

Dennis Wise on TV just said that Jack Butland would be perfect for Chelsea. Someone give him a nudge!
Kepa on his way?
David Ornstein
BBC Sport
Chelsea are in advanced talks to sign Kepa Arrizabalaga from Athletic Bilbao for a world record fee for a goalkeeper of £71m.
The 23-year-old would be brought in as a replacement for unsettled Thibaut Courtois.
The deal would surpass the fee, believed to be up to £66.8m, that Liverpool paid for Alisson in July.
Belgium international Courtois, 26, has yet to return to training and is linked with a move to Real Madrid.
Should the deal for Kepa go through, it would be a club record purchase for the London club, surpassing the £58m they paid Real for Spanish striker Alvaro Morata last summer.
