Bayern Munich made mince meat of Group C, winning all six of their games to storm through on maximum points. They scored 18 times in their games and concede just twice.

You'd expect them to wipe the floor with Viktoria Plzen, but Inter Milan and Barcelona are made of sterner stuff. All three of them were dealt with, though. Barca in particular had a chastening time of it, losing 3-0 at home to the German champions en route to the Europa League.

Right then... Champions League. Where were we?

So much water has travelled under the football bridge in the few short months since the Champions League group stages ended. You'd be forgiven for forgetting how they played out. I had.

With respect to tonight's last-16 ties, here is a little reminder...

Last time a lot of us saw Lionel Messi and Kylian Mbappe play on telly it was in arguably the best World Cup final of all time.

Shall we spoil ourselves by enjoying the highlights of that game again?

Yes, yes we shall...

Lionel Messi starts up front for PSG, after recovering from a hamstring injury.

There is also a start in midfield for 16-year-old Warren Zaire-Emery, after he scored in the 3-1 defeat to Monaco at the weekend.

BBC Radio 5 Live

We'll have everything covered on the live text here tonight, with all the action and reaction from both games.

On BBC Radio 5 Live, there is full live commentary of Tottenham's trip to AC Milan, with build-up starting at 19:00 GMT.

After a three-and-a-half month hiatus, during which we've crammed in a World Cup amongst all the league action, the Champions League returns, showcasing Europe's 16 best teams in a straight two-legged knock-out run to that big-eared shiny cup.

Tonight, we begin with two absolutely belting ties. One is between two of Europe's proper big-hitters, who have both dominated their respective nation in recent years. The other sees the first meeting of two teams since they went toe-to-toe (and forehead-to-forehead in one infamous incident) in one of this competition's most fiercely-contested last-16 ties 12 years ago.

In Paris, French champions PSG take on German top dogs Bayern Munich. Meanwhile, in Milan, it's AC against Spurs.

We'll bring you every goal, big chance, save, card and throat-grab over the next few hours.
