You may have missed the news last week that a number of Champions League rules and regulations have been tweaked for next season.

Players will be able to represent two different clubs in the same European cup competition - as it stands, January signings cannot play for a second club in the Champions League or Europa League if they have already featured in that competition.

A fourth substitute will be allowed in extra time of knockout ties, while 12 substitutes can be named in the finals.

And some Champions League group games will kick off earlier - at 17:55 BST/GMT.

Sevilla are still an awkward side to play against, and they have a range of options they can go to on the bench who are unlike the players they will be starting with.

So one moment you go from facing Luis Muriel to Wissam Ben Yedder, and it is a completely different proposition for a centre-back. You have to adjust, and you have to do it quickly.

I watched Bayern at the weekend. They were outstanding. Franck RIbery, who should really be on his way down now, put in a stellar showing. 2006 stuff.

Fabian: Why is everyone keeping their eyes off Bayern Munchen?; Isn't Jupp Heynckes the same coach who put seven goals past Barca in 2013 when they last lifted it? Sorry Madrid fans but my money is on Bayern this season.

It is absolutely smashing down with rain in Turin now as, on cue, the stadium DJ cues up AC/DC's Thunderstruck.

Top work all round.

For all of Jose Mourinho’s talk of football heritage, you have to respect what Sevilla have done in Europe and knockout competitions.

Not only this season in knocking out Atletico Madrid from the Copa del Rey and knocking out Manchester United from the Champions League, but also what this team has done in the Europa League over the years. This is a team that lives for nights like this.

If that game is no good, we're all going to pack it up and go home...

Manchester City playmaker Kevin de Bruyne speaks to Jermaine Jenas about his team's forthcoming Champions League quarter-final against Liverpool.

Watch the full interview on The Premier League Show, Thursday 5 April, BBC TWO at 22:00 BST.

Manchester City striker Sergio Aguero has been ruled out of Wednesday's Champions League quarter-final first leg at Liverpool with a knee injury.

Aguero has missed the past five games for City and Argentina with the injury.

"Sergio is much better but doctors spoke to him today and he said he still has a little bit of a problem and isn't comfortable," said boss Pep Guardiola.

Liverpool have defensive injury problems, with Joe Gomez, Joel Matip and Ragnar Klavan all ruled out.

Wissam Ben Yedder has scored 10 Champions League goals in 12 appearances – only Adriano (11 apps) has reached 10 goals in the competition in fewer games, while Simone Inzaghi also scored 10 goals in his first 12 CL games.

Of the 43 players to have attempted at least 15 shots in the Champions League this season, Ben Yedder has the best shot conversion rate (36.4%).

Roshimon: Real Madrid for me are the favorites and yeah a Premier league team could win it as well. Very hard to predict and that's the beauty.

Juve, who were 3-1 winners at home to AC Milan on Saturday, have lost only one of their last 75 home games in all competitions (W64 D10), the 2-1 defeat against Lazio on 14 October 2017.
