Ajax were 3 points clear of Lyon with equal head to head (both 0-0 games), with Ajax having a goal difference of +3 and Lyon having a goal difference of -4.
Ajax had to play Madrid, a game where they had two clear cut goals denied, while Lyon scored 6 goals in the second half in space of 20 minutes or something, and Lyon went through on GD while Ajax were knocked out.
And Lyon had scored only 2 goals before this game that was the home against against Zagreb. Zagreb had been woeful in the entire group stage, and had also a man sent off during a Lyon game.
Go Figure.
That winking isn't of much significance really, at least not yet now. There's also an image floating around of a Zagreb player taking betting money, but that image is an old image, much before this game.
He's back in training, hopefully he'll be eased in and be fit for rest of the season.
