We're asking you which managers will be in, out or shaken all about once this thrilling season comes to a close:

Mark O'Neill: I fear for Manuel Pellegrini this summer...

Mandeep Karki: Ancelotti is doing well. And Real have no options after him. But it's time for Wenger to step down.

Iyke Francesc: Van Gaal is a good coach, but I think he should leave. He and Man Utd aren't a good fit.

Under way!

I know quite a few people who have been to a game in Porto who say the Estadio Dragao is one of the very best stadiums in Europe. It looks glorious tonight. Are the hosts going through?

The teams are in the tunnels, there are two in the Bernabeu. Real look confident and calm. The first goal tonight could either end, or kick-start, this tie...

Schalke boss Roberto Di Matteo on ITV: "We want to give a good account of ourselves. We have to try our best and see what comes out.

"The mindset is forget about the last game and try and win the game here. If we score the first goal it is going to be interesting. I don't believe Real are in crisis. The media is making more of it than it is."

Did PSG dominate Chelsea in the first leg, Jose? Well yes. Kind of.

"If to dominate is the number of chances created, yes Paris had more chances than us. If dominating means stopping your opponent from playing, making foul after foul, yes they also dominated. If to dominate is to have the ball but make no progress, yes they dominated. So yes, I think they dominated in every way except the result."

So yes. But no. I see...

Schalke have a 19-year-old in goal tonight. Good luck to you Timon Wellenreuther...

Chelsea boss Jose Mourinho: "A team with fantastic players [PSG] was the team with that record of fouls, making foul after the foul. They were the team that stopped Eden Hazard with fouls all the time, the team that was attacking the man in possession of the ball with two or three players very aggressively.

"They were the team even with a player like Zlatan, a typical attacking player, who was coming back and tackling Hazard whenever his team lost the ball, tackling him from behind to stop a counter-attack.

"I have to be fair, I thought a team from England would never be surprised by aggression, because aggression is in our country. During this season we have played a few times against teams from the Championship in the cups, and we've played teams from League One in the cups and even a team from League Two, Shrewsbury, in the cups. But the most aggressive team was Paris St-Germain.

"For me, that was a real surprise, because for a team with so much quality I was expecting more football and less aggression."

Feisty stuff from Jose...

Schalke have plenty of familiar names in their line-up, captain Benedikt Howedes was a Germany regular at the World Cup, Tranquillo Barnetta has been in the Swiss side for years and the hunter, Klaas-Jan Huntelaar scores goals.

Can they score at least twice in Madrid though? That is the $64m question.

Roy Keane is having a busy week, fresh from his stint with the BBC at Old Trafford last night he's jetted in to Madrid with ITV.

Is Cristiano Ronaldo having a crisis? "If that's a crisis, then God help the other players on the planet," he says...

Nick Valerio: Ancelotti, Klopp, Benitez and Pellegrini will all be on the move.

Sulaimon Adelekan: I dont see any moves in Europe's top clubs

Rizpey: Tom, you say Carlo Ancelotti's time at Real Madrid will come to and end this summer... He is always welcome here at QPR!

He did OK the last time he worked in west London, didn't he Rizpey?

Arsene Wenger at the Bernabeu? I don't see it. Mind you I don't know who they'll go for next...

We're asking you which managers will be in, out or shaken all about once this thrilling season comes to a close:

Adam W from Hull: Wenger and Ancelotti to swap in the summer?

Simon in Runcorn: Maybe Ancelotti comes to Man Utd in a swap with Van Gaal? He seems better suited to England than LVG and he did OK in his Chelsea stint.

Real midfielder Toni Kroos and left-back Marcelo - who is on the bench tonight - are both a booking away from suspension, while Schalke have Klaas-Jan Huntelaar and Marco Hoger treading the old disciplinary tightrope.

Just how important is home advantage in the second leg of the Champions League?

Uefa says that 72% of teams who have had the second leg of their last-16 ties at home have gone through in the last 10 years, although bizarrely that stat flips in the semi-finals.

In the last four it appears to pay to play the first leg at home., external

Chelsea boss Jose Mourinho is giving his pre-match media conference and predicts, among other things, that he'll enjoy a good night's sleep tonight.

"Experience helps us to sleep well tonight. You feel comfortable to play. It's something that you do a lot of times," he says.

"This is [just] one more game, in spite of it being a knockout game and the second leg. So, calm.

"But I think that, during the game, the players will play. We are speaking about teams with very good players, and some of them are very comfortable playing at this level. It's more about them."

Sleep soundly, Jose. But keep across tonight's action with us first, obviously.

If he can find his best form, Cristiano Ronaldo can once more overtake Lionel Messi at the top of the all-time Champions League goalscorers list tonight with a brace. Those two will continue to trade places at the top of this list for the next few years.

Where will the record end up? 100 goals?

Former France captain Blanc also told reporters that he hopes his side can perform better in London than Chelsea managed in Paris.

"I hope we do better than Chelsea did in the first leg," he said. "Chelsea created only one chance and they scored from that. I hope we create more than one chance."

How does he intend for his side to manage that? That no-so-secret weapon, Zlatan Ibrahimovic.

"He's someone who loves the big occasion. He's a player who can score at any time, in any venue, against any opponent.

"I don't think [Gary Cahill and Kurt Zouma] are going to be happy about facing Zlatan."

Well, would you be?
