I think this is a difficult game for Chelsea. I'm surprised N'Golo Kante isn't starting. I know he has been injured and is coming back, but in a big game like this one, I would still have had him in there.

But Thomas Tuchel has liked that Mateo Kovacic and Jorginho partnership - in particular Jorginho.

It's an interesting team, though. Could he have played Thiago Silva? I'm just happy that Tammy Abraham is in the squad because I feel like he deserves this opportunity.

Chelsea

Chelsea boss Thomas Tuchel on their 5-2 defeat by West Brom: "I could not see it coming, even when I watched it after with the video analysis.

"We got a big slap in the face and if it was necessary to remind us how tough it is to have clean sheets and to keep on winning then we have to take it like this.

"We come from a competition where you can lose 5-2 to the 19th team in the league so we are humble with how we approach every game.

‘We play in the quarter-final of the Champions League and once you wish for an opponent, you will lose yourself in some crazy mind games.

"We have the feeling that we are strong enough to overcome Porto but it will be a tough match."

Chelsea

Five changes for Chelsea from the side that started the 5-2 home defeat to West Brom.

Antonio Rudiger, who was involved in a training ground incident with Kepa Arrizabalaga on Sunday, returns.

Mason Mount is also back along with Andreas Christensen, Ben Chilwell and Kai Havertz.

Thiago Silva, who was sent off against West Brom, is on the bench.

Chelsea XI: Mendy, Azpilicueta, Christensen, Rudiger, James, Jorginho, Kovacic, Chilwell, Mount, Werner, Havertz.

Substitutes: Arrizabalaga, Alonso, Silva, Kante, Abraham, Pulisic, Caballero, Zouma, Giroud, Hudson-Odoi, Ziyech, Emerson.

Porto bring in Marko Grujic - on loan from Liverpool - and Luis Diaz to replace suspended last-16 goalscorers Sergio Oliveira and Mehdi Taremi.

Porto XI: Marchesin, Manafa, Mbemba, Pepe, Sanusi, Corona, Grujic, Uribe, Otavio, Marega, Diaz.

Substitutes: Leite, N'Diaye, Ramos, Baro, Mario, Anderson, Martinez, Evanilson, Nanu, Sarr, Vieira, Conceicao.

Bayern Munich have not eased up in the Champions League following last season's triumph and instead have continued right from where they left off.

They have won 18 of their last 19 games in the competition - the other result being a 1-1 draw with Atletico Madrid on 1 December.

They could become only the second team in Champions League history to record a 20-match unbeaten run, following Manchester United between 2007 and 2009.

Without Robert Lewandowski, Bayern Munich are unchanged from the side that beat RB Leipzig in the Bundesliga on Saturday.

That means former PSG forward Eric Maxim Choupo-Mopting starts, as does former Manchester City winger Leroy Sane.

There's three changes for PSG as Colin Danilo, Julian Draxler and Dagba come for the French champions.

Neymar, who was sent off in Ligue 1 at the weekend, and Kylian Mbappe also start.

Both legs of this tie are at the Ramon Sanchez Pizjuan Stadium in Seville, Spain because of Covid travel restrictions between Portugal and the UK.

Today is Chelsea's away game so a 1-1 draw tonight coupled with a 0-0 draw at the exact same stadium next week - also with no fans - would see the Blues go through on away goals.

There is no doubt that Bayern Munich have been the outstanding club side for the past year or more. They won last season's treble of Bundesliga, German Cup and Champions League - and followed that up with three more trophies this season (Club World Cup and Uefa and German Super Cups).

Wednesday's quarter-final tie with Paris St-Germain is a repeat of last year's final, which Bayern won 1-0 for their 21st victory in a row in all competitions.

Bayern's biggest star of all that success has been 32-year-old Robert Lewandowski, who is in the form of his life.

Between last season and this campaign, the Poland striker has scored 101 goals for Bayern in 83 games.

But they will have to do it without him against PSG after he was ruled out for a month with a knee injury.

So this is a chance for Bayern Munich to show how good they are even without Lewandowski's 1.2 goals per game - especially against a team including Kylian Mbappe and Neymar.

The evidence says they will be fine. Their previous 18 games without Lewandowski have ended without defeat - 15 wins and three draws. The last time they lost without him was four years ago in the first leg of a Champions League quarter-final against Real Madrid.

The Jose Mourinho derby. The Deco derby. The Ricardo Carvalho derby. The Paulo Ferreira derby. The Hilario derby. Well, you get the idea.

Ten players have played at least one game for both Porto and Chelsea's first team - although none of them is currently at either club. Porto loanee Malang Sarr could face his parent club, although he has not played for Chelsea yet so is not on that list.

Porto - the only team to score against Manchester City in this season's Champions League - got past Portuguese icon Cristiano Ronaldo and Juventus in the last 16.

Their run to the last eight of Europe is even more surprising since they sit seven points off the top of the Portuguese league and are out of both cups.

And they received a boost at the weekend as Chelsea should have been coming into Wednesday's tie high on confidence after a great run of form - but a 5-2 home defeat by West Brom ended their 14-game unbeaten start under Thomas Tuchel.

To make their preparation even worse, media reports claim Tuchel sent defender Antonio Rudiger home from training the following day after a clash with keeper Kepa Arrizabalaga.

Manchester City are looking in OK shape after beating Borussia Dortmund 2-1, while Liverpool face an uphill battle after losing 3-1 at Real Madrid.

And now it's Chelsea's turn as they face Porto in the Champions League quarter-final first leg - their first game at this stage since 2014.
