#3 Flop: Lasse Schone
It was his lofted cross into the box which de Ligt headed home to double Ajax's aggregate lead after five minutes, but the 32-year-old turned villain in a frantic second-half with a moment of madness. Andre Onana's excellent point-blank save denied Fernando Llorente as Spurs probed and with players packed in a goalmouth scramble, the young Ghanaian attempted to collect the ball between his gloves.
Rather than trusting his 'keeper and leaving it to him though, Schone panicked and attempted to clear his lines. Instead of doing so, he presented Lucas with the ball and moments later, Ajax's three-goal cushion (and two-goal lead on the night) had been erased.
It was a needless action, not least in the middle of a goalmouth scramble, and the Brazilian duly punished him. Typical it was their most experienced player who committed the mistake, where you'd expect better in that situation given the high-pressure environment.
He was their best passer (89.7%) besides Frenkie de Jong, completed four tackles and didn't commit a foul either - but failed to really impose himself in midfield and found himself bypassed far too easily in transition. Unsurprisingly replaced on the hour mark for Joel Veltman, he certainly will be replaying that moment in his mind for days to come.
