The Dane cost a third of the price United paid Chelsea for the Spaniard, but the return this season has not reflected that.
Eriksen is in a particularly impressive run of form, and compares favourably to Mata in a couple of key areas.
|Team||Goals||Assists||Key Passes||Passing Accuracy||Mins Played|
|Juan Mata||Man Utd||5||3||20||91%||1,142|
He has more goals than Mata, and has created double the number of goalscoring opportunities, albeit while playing 300 more minutes.
Even with per game stats taken into account however, Eriksen's 0.39 goals per game betters Mata's 0.33 - While his key passes per game of 2.33 also betters the United's star's average 1.33 chances created per match.
Eriksen has fewer assists despite his creativity, yet it's likely fair to put this down to the superior quality of Manchester United's strikers to Tottenham's.
While Eriksen's starring role against United is assured, Wayne Rooney's impressive role in a deeper area threatens to carve into Mata's individual influence for the Red Devils against Tottenham.
