Chelsea have midfielder Marco van Ginkel back on the bench tonight as well. The Dutchman tore his cruciate ligament 10 minutes into his debut back in August but is available once more.

Left-back Ashley Cole makes his first Chelsea start since 26 January as Jose Mourinho makes six changes from the side beaten at home by Sunderland last Saturday. Striker Fernando Torres, starting against his former club, will seek his first goal since 26 February, while goalkeeper Petr Cech, midfielders John Mikel Obi and Frank Lampard, and defender David Luiz return.

Samuel Eto'o has a knee injury, while right-back Branislav Ivanovic is suspended, and midfielders Nemanja Matic and Mohamed Salah are cup-tied.

Atletico Madrid's on-loan Chelsea goalkeeper starts for the La Liga leaders, but David Villa is on the substitutes bench.

Andrew Valette:, external The football fan in me wants Atletico to win. The evil person in me wants Mourinho to advance and deny his old team La Decima

Jon Mikel Obi and Frank Lampard in the engine room tonight then. I hope Ramires has had his wheat-based breakfast cereal...

Chelsea make six changes from the side which was beaten by Sunderland at the weekend. Fernando Torres starts up front against his old side.

Chris Waddle on BBC Radio 5 live

"Jose Mourinho is good value with some of the things he said and sometimes he goes OTT. That's the way he's always worked since he came to this country. He's always had that little bit of controversy.

"This stadium tonight will be electrifying. Outside in the street there are masses of red and white. They all up for this game. It's going to be very interesting because they are very similar in their style of play. If the match can compete with the atmosphere we're in for a cracking game.

"But Mourinho is very experienced at this level and he will set his team up for 0-0, a clean sheet and if they can nick a goal he'll probably think they will go through. But Atletico are playing with a lot of confidence and with this crowd behind them it will be a very tricky tie."

Suggesting that Fernando Torres was once a firm fans' favourite at Atletico Madrid is something of an understatement.

The Chelsea striker will be hoping to help fire his side into the Champions League final by defeating the club where he made his name before joining Liverpool in a £25m move nearly seven years ago.

And when the now 30-year-old first steps onto the Vicente Calderon turf to limber up for Tuesday's first leg, Torres is sure to be granted a warm reception from the supporters who once idolised him.

Spanish football writer Andy West says that Torres may yet make the move back to his boyhood club for good in the summer. Swap deal for Diego Costa anyone?

Chelsea found a late, late goal to beat Paris St-Germain in the last round, but what faces them now?

Only an Atletico Madrid side who knocked Barcelona out in the last eight and who lead La Liga by four points.

Madrid are just seven games away from a historic double, and with Chelsea's own on-loan goalkeeper Thibaut Courtois at one end and the prolific Diego Costa at the other, they have the tools to shut down Jose Mourinho for another season.

The home crowd can also play a part tonight.

The contribution from the crowd will come in waves: a deceptively quiet few minutes will be shattered by an explosion of noise when the home crowd start to sense that the Rojiblancos are getting on top.

When Chelsea enjoy dominant passages of play, they will have to withstand the ear-splitting noise of 50,000 Atletico fans simultaneously screaming and whistling in defiance.

And manager Diego Simeone will do his utmost to ensure the fans are involved. He can often by seen playing the role of cheerleader, turning dramatically towards the stands and frantically raising his arms to request more noise - and those exhortations are never declined.

Ryan Giggs - interim boss at Old Trafford - joins a long list of men to step into the role of Premier League manager this season.

The current list of the 20 men in charge bears little or no resemblance to those who began the season in August - if anyone could have predicted that Giggs would be lining up alongside the likes of Pepe Mel, Neil Adams, Felix Magath, Garry Monk and Ole Gunnar Solskjaer by now they could have printed their own odds at the bookies.

Of the current crop only Arsene Wenger, Alan Pardew and Sam Allardyce started their current job before the summer of 2012...

Mike, London via text: Couldn't imagine JM putting up with Nani and Ashley Young!

Andrew via text: Following Sir Alex Ferguson was always going to be an impossible job for whoever took on the role, even Jose Mourinho. The constant comparisons with the old boss would have been too much for anyone to cope with. However, with Mourinho in charge Manchester United would not be sitting 7th in the table.

Paul, Hexham via text: What about Steve Bruce to replace Moyes? A fine United pedigree and one of the few Fergie players still managing at top level.

MOTD presenter Gary Lineker

"There's no question Manchester United are a club in crisis because they've not qualified for the Champions League, they've lost a manager just before the transfer window starts, and they are in a worse situation than they were in 12 months ago."

JP Finn: , externalMourinho may yet turn up at Old Trafford. Would not bet against it. Any motivational issues that may exist would be banished.

Wale Ibraheem: , externalJose would have turned Old Trafford ino another fortress even with the same current players people think are not good.

James Benson: , externalHard to see Mourinho doing that much of a better job than Moyes, with the squad he had. But then again, he is the Special One.

Atletico Madrid's on-loan goalkeeper Thibaut Courtois has long been lined up to replace Petr Cech at Chelsea - eventually. The Belgian has been a brilliant signing for Atletico and has been cleared to play against parent club Chelsea tonight.

Uefa waived a fee that Atletico were due to pay Chelsea after the two clubs were drawn together in the semi-finals.

Atletico president Enrique Cerezo had said his club could not afford to pay the fee Chelsea wanted for the two games, reportedly about £5m., external

But Uefa said the agreement was "null, void and unenforceable", allowing the La Liga leaders to select the 21-year-old for the two-legged semi-final.

We should have team news with you shortly.

Alex, London via text: With Jose as manager, Man Utd would have probably have gotten more big name transfers over the summer. Mourinho has a pedigree Moyes never had.

After 26 years of Sir Alex Ferguson Manchester United fans now face the prospect of a second new manager inside a year.

But who will it be? Club legend and player-coach Ryan Giggs has stepped into the breach for now, but he is unlikely to be offered the job on a permanent basis.

Netherlands coach Louis van Gaal, Borussia Dortmund boss Jurgen Klopp, Atletico Madrid's manager Diego Simeone and Paris St-Germain's Laurent Blanc have already been tipped as possible successors.

However, Klopp has ruled himself out of the job, the 46-year-old telling The Guardian:, external "Man Utd is a great club and I feel very familiar with their wonderful fans. But my commitment to Borussia Dortmund and the people is not breakable."

The Daily Telegraph suggest United will make discreet moves to see if Pep Guardiola can be persuaded, external to leave Bayern Munich. I think that might be a short phone call...

Tom, Portishead via text: Jose would be everyone's choice surely? Moyes was screwed from day one with that squad. Didn't help himself though, why would the owners back him with a war-chest after the last transfer fiasco?

WWJD? That is, what would Jose have done at Old Trafford?

We may never know - or perhaps Mourinho will rock up in Manchester one day. But I'm interested in your thoughts.

As Jose prepares for a Champions League semi-final with Atletico Madrid, with a possible third winners' medal on the horizon, what would he have achieved this year with the current Manchester United squad?

Where would they be in the league? Would they still be in Europe? Who may he have signed? Who would have been frozen out, Ashley Cole style?

Let me know. You can text in on 81111 (UK Only), or tweet us using the hashtag #bbcfootball., external

We will never really know how close Jose Mourinho came to becoming Manchester United manager last year.

The man himself said last June that: "I would have turned down every job in the world - the Manchester United job, every one - for Chelsea."

But was he just saying that after seeing Moyes installed at Old Trafford? Would he have loved the chance to step into Sir Alex's loafers?

I'm guessing he'll be asked before and after tonight's game. He won't be happy about United stealing the limelight...

If you've been sleeping under a large rock for the last 48 hours there is a chance that you may have missed the major, major news of the day:

Manchester United have sacked manager David Moyes only 10 months after succeeding Sir Alex Ferguson.

United, who lie seventh in the table with four games remaining, are guaranteed to record their lowest points tally in the Premier League having struggled at Old Trafford in particular this season.

Under Moyes, they have lost six league games at home, been beaten in the FA Cup by Swansea at Old Trafford and were unable to prevent Sunderland defeating them in the Capital One Cup semi-finals.

It has not gone well...
