Diego Costa, Atletico Madrid
WhoScored rating: 8.52
The feisty Brazilian certainly seems to sum up the character of his team; Atletico have battled their way to the knockout stages of the Champions League (with an unbeaten record it's worth noting) and certainly won't go down without a fight.
They face an unfancied AC Milan this week, and while they are favourites to progress, they'll need Costa to be at his best to make sure they do just that.
He's got four goals and one assist in just three games - and after something of a lean spell in La Liga, Costa would love to snap his slump on the grandest stage of them all.
