#3 Dele Alli is really good at football
Dele Alli is only 22 years old, but it feels like he's been around for quite a while now, doesn't it? He burst into prominence in the 2015-16 season, scoring 10 goals and assisting 9 in the league despite joining in January.
Since then, he's gone on to become one of the best goalscoring midfielders in the English top division, contributing 25 goals (18G 7A) in 16/17, then 19 goals (9G 10A) in 17/18. He has not been in the same sort of form this year, having a slow start for the new season, but he's slowly springing back into life and was at his best tonight when it mattered the most against arch-rivals Arsenal.
His goal and performance tonight were 10/10, and a stark reminder for those who'd forgotten that Dele Alli is one of the best midfielders in England, if not Europe.
