So Benjamin Mendy, Raheem Sterling, Rodri and Gabriel Jesus have made way,

Aguero, Oleksandr Zinchenko, Fernandinho and Riyad Mahrez are on.

Here comes Sergio Aguero.

Is he wearing a Diego Maradona tribute top underneath his shirt?

We'll find out if he scores in the closing minutes.

Foden to Silva who drags it wide. More frustration.

Double City change coming up. Raheem Sterling's work is done. He's coming off.

His back-heel assist has been the highlight of this game.

Another home change. Midfielder Andreas Bouchalakis, who once played for Nottingham Forest, is on.

Lovely play by Joao Cancelo to pick out Phil Foden who heads wastefully into the side-netting with team-mates waiting in a better position.

First change of the game and Mohamed Drager makes way for attacking player Marios Vrousai.

If Olympiakos nick an equaliser Pep Guardiola's post-match interviews are going to make great telly.

Another attempt by Joao Cancelo. The defender is determined to leave Greece with a goal to his name.

Olympiakos won't take too any chances, they're trying a little bit, trying to push the midfield a bit further on but they're not holding the ball up well enough so they end up falling back.

There's plenty of teams out there that play a very defensive way, you go 1-0 down it's fine you give it five or ten minutes at the end to see if you can nick it with a corner or a free-kick. That can still be a game plan to get a point.

How's that not a penalty?

Ruben Semedo takes a grab as Gabriel Jesus and the Brazilian goes down inside the box.

Nothing.

Nice attempt by Joao Cancelo, a low arrowed whack which forces Jose Sa to get down and save. City are nudging towards 20 attempts on the Olympiakos goal - and we've still got half an hour remaining.

Olympiakos still haven't had a shot or a touch in City's box.

Exactly what was their plan for this game?

Time to give Sergio Aguero a run out or save him for Burnley?

Come on Pep, get him on.

Ruben Dias becomes the second City player after Raheem Sterling to be cautioned after stopping Olympiakos from taking a throw-in. All a bit silly really.

Paul: I know they say every team has earned their place in the champions league but olympiakos really are scraping the bottom of the barrel in terms of quality. Wonder even if they know what "quality" means. One of a few teams who are the dregs of European football.

Olympiakos look a shambles at the back. So casual, so sloppy. They give the ball away again in a dangerous position and after Phil Foden has a shot charged down, Ilkay Gundogan hammers the loose ball just wide.

Back in Piraeus and there's not a lot going on in the opening exchanges of the second half. Olympiakos are definitely trying to press more but City continue to dominate possession.

Bernardo Silva has had a tame effort but that wasn't going to trouble Jose Sa.

Mohamed Salah returns to the Liverpool side as Jurgen Klopp makes five changes from the weekend's win over Leicester City.

Divock Origi also comes into the team, alongside Rhys and Neco Williams and Konstas Tsimikas.
