One of the great radio 5 live debates here; would Zlatan Ibrahimovic sign for Leicester in the summer?

Not a sentence you could imagine 12 months ago!

Chelsea

Chelsea make just one change from the first leg in Paris as left-back Baba Rahman is replaced by Kenedy. Captain John Terry remains sidelined and defender Branislav Ivanovic skippers the Blues in his absence.

Chelsea XI: Courtois, Azpilicueta, Cahill, Ivanovic, Kenedy; Mikel, Fabregas, Pedro, Willian, Hazard, Costa. 

A groin injury to Marco Verratti forces PSG boss Laurent Blanc into one change from the first leg as the midfielder is replaced by Adrien Rabiot. Striker Edinson Cavani is again on the bench.

PSG XI: Trapp, Marquinhos, Silva, Luiz, Maxwell, Rabiot, Motta, Matuidi, Di Maria, Ibrahimovic, Moura.

Last night saw the first Champions League ties to come to a conclusion, as Real Madrid saw off Roma and Wolfsburg beat Gent. 

Who will join them in the last eight?

Zlatan has bagged 32 goals in 39 games for PSG this season.

Surely the top clubs in England would fall over themselves to sign him up this summer?! Wouldn't they...?

Leicester?

"There is an air of arrogance around Zlatan, as there is with all of the top players. He is advertising the fact to the Premier League as he is out of contract. I don't think any of the top four would take him but maybe someone just below that.

"He will be a handful tonight."

"Age is just a number," said Zlatan Ibrahimovic in the build-up to tonight's game.

"People say I'm old, but I'm only warming up."

The 34-year-old is out of contract this summer, could he be finally coming to England?

Please...

Zlatan has scored eight goals in 37 Champions League knockout games. In the group stages, he has found the net 38 times in 79 games.

Flat-track bully...

He doesn't look especially sure about tonight's game does he? But tweet a dog in a kit and I will use it...

A very simple, straightforward vote for you take part in tonight. Which side will progress to the last eight - Chelsea or Paris St-Germain?

We could go to extra-time or even penalties if tonight's game finishes 2-1 in Chelsea#s favour. The Blues are in the knockout stages of the Champions League for the 12th time in the last 13 seasons. They've reached the quarter finals on eight of these occasions.

PSG have reached the knockout stages of the Champions League for the fourth consecutive season, their best ever run. They've been eliminated in the quarter finals in the last three campaigns.

BBC Radio 5 Live

Mark Chapman is in the presenter's chair on radio 5 live this evening as he brings build-up to all of the night's action from Stamford Bridge.

Tune in now, before full commentary from John Murray and Martin Keown.

Chelsea captain John Terry misses tonight's Champions League last 16 game with Paris St, Germain with a hamstring injury.

He is consoling himself by mingling in the media room - but how Chelsea's fans would love to see him out on the Stamford Bridge pitch.

These two clubs have very recent history, with Thiago Silva's late goal giving PSG victory on away goals here last season. In 2014 Demba Ba's late strike put Chelsea through to the semi-finals in similar fashion.

This latest instalment is delicately balanced, with PSG holding that slight edge from the first leg.

"Can Cesc Fabregas do a job and sit in midfield? I don't believe he can. Chelsea have to go and get that goal but this tie could go all the way. Playing Fabregas in a two in midfield is a big call for me. Midfield is where the game will be won or lost."

Chelsea

Just the one change from the Chelsea team which started the first leg three weeks ago - and it's a big call. Kenedy starts at left-back. 

Paris St-Germain hold a narrow, but potentially crucial, 2-1 lead going into tonight's game thanks to victory in Paris last month.

Who had money on a Jon Mikel Obi goal?! Extraordinary.

The far more frequent goalscorers Zlatan Ibrahimovic and Edinson Cavani ended up winning the night, but Mikel's strike, an away goal, could also prove potentially crucial come bedtime this evening.

These two sides also met in 2014, and again away goals were the deciding factor. Remember Demba Ba's stoppage-time goal which won it?

Could it be a third nailbiter in a row between these two?

The Champions League may not be quite predictable enough for some just yet, but it still manages to routinely throw up familiar match-ups in the knockout stage,

Three hundred and sixty-three days since Paris St-Germain knocked Chelsea out of the Champions League at Stamford Bridge, they are presented with a repeat chance tonight.

Last year it was centre-backs Thiago Silva and David Luiz who grabbed key away goals for PSG, as Zlatan Ibrahimovic saw a contentious red card.

Who will be the main men tonight? Will Laurent Blanc's boys come out on top or is Guus Hiddink's stint in charge set for more cup glory?
