With first-choice Thibaut Courtois given the night off, if something happens to Petr Cech tonight, we could see a debut for 19-year-old Mitchell Beeney.

If you recognise the surname, it might be because his father, Mark, is a former Leeds keeper and now works as a goalkeeping coach with Mitchell at Chelsea's Under-21s.

In more half-time news, it's Maribor 0-0 Schalke at the break.

That result would see Sporting qualify, but one Schalke goal would take Roberto Di Matteo's side through instead.

It's also half-time in Rome, with Manchester City being held 0-0 by Roma - a result which would eliminate the English champions.

You can read a separate live text commentary on that here.

Sure, who needs injury time? Chelsea in control at the break.

Chelsea break with Cesc Fabregas playing a ball out left to Mohamed Salah and his cross is just headed away from Diego Costa out for a corner.

The corner is cleared only as far as Salah, whose first volley is deflected back to him and his second attempt is well over the bar.

Andre Carillo looks like he's behind the Chelsea defence but his cross is cleared, he's been Sporting's dangerman so far though.

We're approaching half-time in London.

Cesc Fabregas plays a ball out to the left wing to find Diego Costa, who barges his way into the box, he looks like he's lost it twice and then he does - Sporting defender Maurico boots the ball off the Spain international with the high deflection landing in the hands of Rui Patricio.

Andre Schurrle is having an outstanding game, and this time he plays a through-ball to Diego Costa, whose shot is blocked by a Sporting defender.

Schurrle would surely be first pick at nearly every other Premier League club.

Sporting have a chance to score. Maybe even two. Diego Capel's header is blocked by Cesar Azpilicueta and Islam Slimani is unable to hook home the rebound - Capel eventually poking it at Petr Cech.

Slimani wanted a penalty for a supposed push in the build-up too.

John Mikel Obi sidesteps William Carvalho like he was the Brazilian playmaker rather than a holding midfielder. The Nigerian hits a strong pass at Diego Costa, who is unable to control it.

Jared Maobe:, external I thought Jose Mourinho has been crying that Diego Costa isn't fit! Why play him in a meaningless midweek match?

Nemanja Matic is the latest Chelsea player to have a shot, but his half-volley from Mohamed Salah's pullback goes just past the top corner.

Sporting's hopes now probably lie entirely with Maribor.

Adrien Silva comes forward for Sporting Lisbon but his ball to Islam Slimani is overhit and goes out for a goal-kick. More frustration for Sporting.

And moments later Andre Schurrle has another shot, which is deflected wide. The Chelsea winger is hungry for goals.

Chelsea are in complete control at Stamford Bridge, Andre Schurrle almost doubles their lead but his half-volley is palmed away by Rui Patricio.

I don't expect this to end 2-0.

This team would still challenge for the Premier League title, no doubt.

So what does this mean for second place in Group G? Well Sporting will still qualify if Schalke fail to win in Maribor - that's 0-0 at the moment.

Is this game over for Sporting Lisbon already? Nemanja Matic plays the ball across to World Cup winner Andre Schurrle, who strokes the ball into the corner of the net past the reach of Rui Patricio from 18 yards. Expert finish.

Twelve passes in the opposition half for Mikel so far.
