Chelsea are being frustrated by Real Madrid, who are the masters of situations such as this. Just one more goal might be enough to rekindle hope but they cannot afford to miss chances like the one Romelu Lukaku squandered.

Fifteen minutes to go and this is when things will start to get a bit nervy for Villarreal as they look to hold on to a priceless result. Joshua Kimmich whips in a dangerous cross but Geronimo Rulli is alert to it.

Dani Carvajal is down now, he got a knock from Cesar Azpilicueta and will happily eat up a few minutes. Real would love to take a two-goal lead back to Madrid.

Stavros Makro: You have Benzema and you have Romelu Lukaku. The comparisons are inevitable and not in favour of the Belgian (after that free header especially).

Toni Kroos will get a rest, with teenage France midfielder Eduardo Camavinga the man to come on.

The home fans are in full voice again now, driving their side forward. But they have their hearts in their mouths once more as Edouard Mendy just about gets away with a heavy touch inside his own box!

A huge miss by Lukaku, that should have been 3-2. He's got his head in his hands because that is a huge opportunity.

He tried to put too much execution on it and doesn't even get it on target - that should be a goal for someone of his level.

The difference is, if that's Benzema at the opposite end, that goes in.

They're getting closer, but can Chelsea find another goal to take to the Bernabeu?

Chelsea are pressing now!

Romelu Lukaku is giving Real Madrid something to think about and his pressure on Casemiro sees the ball fall to Mason Mount, who whips an effort just over the crossbar.

Another chance for Romelu Lukaku!

He's completely unmarked just outside the six-yard box as a deflected cross leaps up into his path, but the forward flicks a header narrowly wide of the far post.

This game is wide open now!

Alphonso Davies hits a decent effort at goal but straight at Geronimo Rulli before Arnaut Danjuma has an effort blocked inside the Bayern box at the other end.

A few tackles flying in now, with Kai Havertz back in his own corner to win the ball for Chelsea.

Chelsea work it forward down the right and Reece James picks out Romelu Lukaku in the middle, but he can't engineer a proper header on goal.

Dani Carvajal is showboating now, popping the ball round Mason Mount and looking to run past the Chelsea man, who catches his shoulder and brings the Real full-back down.

Pau Torres makes a huge challenge to deny Leon Goretzka, who is straight into the action after coming on.

Just under 30 minutes to go. Can Bayern find a way back into this?

Here are the Chelsea changes, with Christian Pulisic and Jorginho making way for Romelu Lukaku and Ruben Loftus Cheek

A change for the visitors as well, with Nacho on for Eder Militao.

Double change for Bayern Munich as they look to get back into this. On comes Leroy Sane and Leon Goretzka for Serge Gnabry and Thomas Muller.

Romelu Lukaku whips of his trackie bottoms and will be the man tasked with getting Chelsea back into this Champions League quarter-final contest. Ruben Loftus Cheek is also getting ready.

Alfonso Pedraza comes on for Francis Coquelin and is immediately involved as he drives a shot into the sidenetting.

Bayern have been better in this half but have still not managed a shot on target and instead it is the hosts who look the most likely to score again.

Eder Militao is down once more after going shoulder to shoulder with Kai Havertz, might have twisted awkwardly in that challenge. Chelsea look set to make a change, too...

Real are sitting deep and inviting Chelsea to try and break them down, but they also have that threat on the counter and the Blues will be wary of that. Christian Pulisic tries his luck from distance but it is easy for Thibaut Courtois.
