#2 Flop: Dan-Axel Zagadou

We're all aware that big moments in matches can often change the complexity of hotly-contested matches within an instant. Dan-Axel Zagadou, 19, will need to learn from a memorable - but certainly not positive - experience at Wembley, where he was ultimately exposed by a ruthless Tottenham side in the second half.
Before then, he squandered a great opportunity to gift Dortmund the lead in stoppage-time. It would have provided them a crucial away goal at least, but alas, the Frenchman's headed effort was saved by compatriot Lloris.
Sancho's delightful ball was perfectly-weighted for him to meet, with Juan Foyth alongside him. However, the young Argentine did enough to stifle Zagadou's effort enough and take some of the pace off his eventual strike.
He was the only defensive-minded player for both sides not to record a completed tackle and crucially failed to clear his lines moments before Son opened the scoring. If you watch the replay, you'll see that he gave the South Korean a yard of space behind him to exploit, rather than trying to track him tighter and keep alongside him. He missed the attempted header and Son proved the beneficiary after Vertonghen's fantastic cross.
At such a crucial point, so early into the second half, it set the tone for the remainder of this game. Spurs could smell blood and knew their opponents were there for the taking, particularly given how unconvincing Zagadou looked at times in central defence. You could certainly tell that this was his first start since early December.
