Good evening and welcome to live coverage of Chelsea v FC Basel in the Champions League. We'll have the teams for you shortly.

And that's it - Chelsea's second defeat in a row, and they get their Champions League campaign off to the worst possible start.

Cahill launches forward and it nearly drops for Oscar, but Basel clear.

Streller tries to keep the ball on the left, but Cahill dispossesses him. Not long left for Chelsea now.

Mata tries a lifted ball into the box, but Schar heads clear.

Eto'o has a chance to equalise, but his toe-poked shot is easy for Sommer.

There will be four minutes of added time.

Hazard tries to create something, but it's easily cleared.

Change for Basel - Salah goes off to be replaced by Taulant Xhaka.

Only a few minutes left now - can Chelsea salvage something?

Schar goes off for treatment, but is back on after a little attention.

Schar could be hurt here after getting a fearful kick on his calf from Ba.

Hazard pokes through to Ba in the area, but Schar gets there first and clears.

Almost another for Basel, as Delgado shoots from the edge of the area, only for it to be blocked. Chelsea rocking here.

Chelsea have really been poor since Basel's equaliser - that goal was coming.

GOAL! STRELLER PUTS BASEL IN FRONT! Remarkable scenes. Too simple for Basel, as Streller gets in front of Cahill at the near post and heads in a corner.

Another half-chance for Salah, who just fails to get to a through-ball ahead of Cech.

Ba pulls out to the right and looks for the cross, but it sails out on the far side.

Break through the middle by Streller, who tries to play in Schar, but Ivanovic just cuts out the pass.

Interesting to see how Chelsea set up now - looks like Eto'o has been pushed out to the left, with Oscar and Mata in front of Mikel, and Hazard nominally on the right.

Double change for Chelsea - Van Ginkel and Lampard are replaced by John Obi Mikel and Demba Ba.
