As expected, Ralf Rangnick makes 11 changes to his Manchester United line-up - and doesn't even keep any of his starting line-up from Sunday's game against Crystal Palace in reserve.

Robbie Savage's son Charlie is on the bench and is one of four players who could make their debuts.

Of the five outfield substitutes, there is a grand total of four first-team appearances, all of them off the bench - three for Shola Shoretire and the other for defender Teden Mengi, who spent last season on loan at Derby.

Steve Conroy: Not sure it matters whether Chelsea are top or second. And the side the manager has picked seems to confirm this.

Good defending by Andreas Christensen to stop Malcom, but moments later the Brazilian cuts in and has a shot saved by Kepa.

Now at the other end Ross Barkley's long-range shot is held by the home keeper.

Zenit make a sub as Andrey Mostovoy replaces Wendell, who hurt himself while sliding.

Manchester United are already through so Ralf Rangnick has opted to completely change the team that started the 1-0 win over Crystal Palace on Sunday.

There are 11 changes with Amad Diallo and Anthony Elanga among the starters.

Cristiano Ronaldo is not involved at all.

The second half begins. Chelsea need at least two goals in the games to go their way or else they'll finish second.

Chelsea have conceded seven goals in their last four games, as many as in their previous 19.

They have conceded two or more goals in consecutive matchesfor the first time since August 2020 (2-1 v Arsenal in FA Cup, 4-2 v Bayern Munich in Champions League).

Some 27% of all Champions League goals scored by Iranian players have come against Chelsea (4/15) - Ali Daei (2) in September 1999 for Hertha Berlin, Mehdi Taremi in April for Porto and Sardar Azmoun today.

Claudinho is only the fourth player to score a Champions League goal against Thomas Tuchel's Chelsea, after Mehdi Taremi (Porto), Karim Benzema (Real Madrid) and Federico Chiesa (Juventus).

Juventus are doing what they need to in Italy and, as it stands, are heading into the last 16 as Group H winners.

They lead 1-0 after Moise Kean headed in from Federico Bernardeschi's superb outside-of-the-boot cross in the 18th minute.

That goal came after Daniele Rugani had headed wide from a corner and Kean had fired into the side netting from 15 yards out.

Malmo have offered little as an attacking threat in the first half.

That was quite something.

Chelsea started very well and ended up being cut apart with ease.

As things stand, they're finishing second behind Juventus.
