The hero of the last round, Demba Ba, will have 90 seconds of action as he replaces Willian.

Diego Costa does see a chink in the Chelsea defence, finding half a yard of space to put in a header but he can't get much power behind it and Mark Schwarzer is able to make a comfortable save.

FIVE minutes added on by the sadistic Jonas Eriksson. Madrid still come in search of a breakthrough, still they come up against a black wall.

...which David Luiz clips over the bar from 20 yards. One minute of the 90 left.

Good play from Fernando Torres on a rare touch, he skips past Miranda and is brought down for a free-kick and a booking. Dangerous spot here...

Ryan Hazelgrove:, external Real Madrid and Bayern Munich must be licking their lips at the prospect at playing Chelsea or Atletico Madrid!

Martin James:, external PSG played poorly against Chelsea as well, think that's a coincidence? Jose = Genius.

Graham Oxley:, external Cannot believe people are doubting Diego Costa because they have watched one game. 27 goals in La Liga is no slouch.

Juanfran in space, you know what's coming, it's a great cross this time and Diego Costa leaps well to power in a header - brilliantly blocked by Gary Cahill. Superb defending.

Two minutes left...

Is this the man to end the stalemate? Spain's record scorer David Villa replaces Raul Garcia. He has six minutes to make an impact.

"Atletico have struggled to create anything. They've got Valencia at the weekend and they are in good form so it will be difficult for them when they to come to Chelsea next week."

No sign of a Middlesbrough comeback as Reading lead 2-0 midway through the second-half. Adam Le Fondre comes close to making it three, but the forward's header is saved by Dimi Konstantopoulos.

Chelsea are up against a lower-league style going over as Atleti continue to pump crosses in. Ashley Cole scuffs one clearance out and Raul Garcia has a free swing but slices wide.

Garcia then heads over the top. Seven minutes for Chelsea to hang on.

Luce Fenner: , externalComing away from the Calderon with a 0-0 & the injuries/suspensions we have & have sustained in the match is a great result.

Andrew Reyes:, external English fans complain about European teams feigning injury. Chelsea players constantly on the floor time wasting.

Rezza Sait:, external What's all the hype about Diego Costa? He plays like a Spanish Olivier Giroud.

Atletico fancy a header at the back stick - Arda Turan is the latest to steam in and head wide but the referee had already given a foul.

Into the last 10. As Chrissy Waddle says, this has not been pretty but so far, so OK for Chelsea.

"Chelsea have done a job tonight. It's not been pretty but it's been effective."

Chance! Raul Garcia rises to meet Juanfran's cross from the right but he can't keep it down.

Brendan Rodgers will be taking a deep interest in the injuries to John Terry and Petr Cech ahead of the game at Anfield on Sunday...

The best save of the night as Mark Schwarzer stretches to push away Gabi's dipping free-kick. Into the last 15 minutes, Diego Simeone doing his best Bond villain impression on the sidelines.

All his best laid plans are coming to nothing.

And now the title's within touching distance as Lloyd Dyer deservedly puts Leicester 1-0 up at Bolton, who have 25 minutes left to mount a response.

After all that Jon Mikel Obi is booked, as is Atletico captain Gabi.

That means that Frank Lampard, Mikel and Gabi will all miss next week's second leg.

More handbags after a Frank Lampard handball. Atleti want a second yellow card for the now Chelsea captain, it's all scuffling off the ball.

The injuries mount up for Chelsea as now John Terry comes off. Andre Schurrle takes his place, so they need a reshuffle. David Luiz goes back into defence.
