I expect Liverpool to go to Marseille and win - the result they need to definitely go through to the knock-out stages.
Their defeat by the French side at Anfield in October was a low point in Liverpool's Champions League history because it was probably the worst they have ever played - it was mind-blowingly bad.
But they will be better than that this time.
Rafa Benitez's side were starting to hit form until they ran into Reading, with a lot of his top players playing well, but that result will give them extra incentive.
It's not a foregone conclusion that they will make it on Tuesday but I think they will and it is imperative they do.
The Premier League is the priority for the club and their supporters but at the same time the massive revenue that will be generated by coming through the group stages is important too.
And then there is the excitement of the knock-out stages. You want to be involved there and competing for the Premier League title at the same time come March. That's what big-time football is all about.
There has been a lot of criticism of Benitez's rotation policy this season.
What you have got to do is play your strongest team and get a bit of momentum and impetus going.
If you are doing well then that gives everybody a bit of confidence, and then you can maybe rotate.
But if you are struggling, and Liverpool were for a while, then you have to play your strongest team and I think to a certain extent he has tried to do that recently.
He has reaped the rewards because not only are they playing well but they are scoring lots of goals and not conceding many either.
They have scored 22 goals in their last six games. That is very healthy and, again, that breeds confidence.
Every time they go on the pitch they must be thinking they are going to score goals and win, which is great for the club and their fans.
This is a big week in their season though - five days after the Marseille match they have got Manchester United in the Premier League - and those two games could set up their season.
Liverpool's American owners Tom Hicks and George Gillett arrive the day before the Manchester United match but I think their dispute with Benitez over the club's transfer policy will blow over.
The most important thing is what happens on the pitch and, if they keep winning, then there will be no problems between Benitez and the owners - it's only when teams are being beaten that there are ever any problems.
