#4 Christian Eriksen vs Nemanja Matic
The wily Danish playmaker vs the hard-nosed Serbian enforcer; sounds a bit cliched, but it is what it is... there are few better at their jobs than Christian Eriksen and Nemanja Matic, and while the Serb was able to keep his Danish antonym quiet during their first match at Old Trafford, at Wembley Eriksen wreaked havoc.
Dropping deeper than usual to swamp the midfield alongside Dele Alli and Mousa Dembele, Eriksen played Matic off the park that day, and the United man will be keen to extract revenge. If he can stop the Dane from playing his natural game, Spurs' passing rhythm and subsequent forward momentum will get drastically affected but if Eriksen can dominate the Serb, it'll leave United's fragile backline hopelessly exposed.
It's a winner take all duel, this.
