Hello and welcome to our LIVE coverage of Bayern Munich v Olympiacos. We'll have build-up and team news over the next 45 minutes before full text commentary.

This game is over as a contest. Now it's just a question of how many goals Bayern want. Unfortunately (for the Greek fans), the answer seems to be 'a lot'.

Kimmich shoots wide after a good lay-off from Vidal. The Bayern fans are in fine voice, and who can blame them.

The movement and attacking intent from Bayern has been hugely impressive. Costa has been drifting all over the place, so is Muller (as ever) and it's proving incredibly tough for the visitors to deal with.

Vidal shoots wide, but still the attempts keep coming. That change for Bayern may free up Vidal slightly from his deep midfield role.

Robben has felt a slight twinge and there's no point risking injury at this stage. Off he goes, with Kimmich coming on.

Bayern take a breather by keeping the ball for a couple of minutes in the centre of the park. It may be a breather for them, but it looks exhausting for the chasing Olympiacos midfielders.

Lewandowski again. Wide again.

Olympiacos are being torn apart. The gulf in class is ridiculous.

One of the great things about this Bayern side are how unselfish they are in attack. In the past Robben would never have turned down an opportunity to go for goal, but Guardiola's great gift is to get the maximum out of already world-class players, and he's certainly doing that with this squad.

Lewandowski's shot takes a sliver of paint with it as it slides agonizingly wide after a wonderful pass into him from the impressive Costa. Bayern are creating chances at will and this could end up in double figures at this rate.

A heavy defeat for Olympiacos would leave Arsenal with a glimmer of hope of still qualifying, but the Gunners need to win tonight and make sure things go their way in the next round.

GOOOAAALLL!!! Thomas Muller makes it 3-0 to Bayern. This is a rout! Lahm's dinked cross is headed back across by Lewandowski to Robben, who in turn opts against going for goal to put it on a plate for Muller. 3-0.

If the visitors could have kept it tight and played on the break then they had a chance tonight, but now that chance is gone and they are going to have to switch on quickly before this gets embarrassing.

GOOOAAALLL!!! Robert Lewandowski makes it 2-0 with an emphatic finish. Coman cuts inside and looks to shoot, but his effort strikes Lewandowski on the way through and breaks nicely for the striker to tee up an effort of his own. 2-0. Too easy.

Both Muller and Costa are playing in more central roles than they are used to tonight and are making the most of the opportunity. The movement from Bayern in the final third is frightening.

Muller flicks a clever shot goalwards, which takes a deflection and wrong-foots the keeper, but the ball drifts just the wrong side of the post.

That was far too easy for Bayern and a worrying start for the visitors.
