Took me a while to figure out what your first paragraph meant. Is that right?
Had a check, he was wrong about the Herrera penalty v Liverpool and Martial v Liverpool. Carrick passed it to Herrera who won the penalty and Schweinsteiger passed it to Young who assisted Martial
OG v Spurs - not involved
Januzaj v Villa - Mata assist
Mata v Swansea - Mata goal
Blind v Liverpool - Mata assist
Herrera v Liverpool - not involved
Martial v Liverpool - not involved
Martial (1) v Southampton - Mata assist
Martial (2) v Southampton - not involved
Mata v Southampton - Mata goal
Depay v Sunderland - Mata assist
Rooney v Sunderland - Mata pass to Martial who assisted
Mata v Sunderland - Mata goal
So that's 4 goals he wasn't involved in, still pretty good.
