The Argentine might not get the plaudits, but he played a big role in the victory.
Michail Antonio, Diafra Sakho and Dimitri Payet scored the goals in the final 11 minutes to down the 10-man Toffees, but the Argentine's contribution should not be overlooked.
Despite being 5 ft 5 in height, Lanzini was arguably the biggest player on the pitch in some ways, clocking over 100 touches and recovering possession for his side on nine occasions - more than any other outfield player.
The diminutive midfielder also completed 82 of his 89 passes and it is clear that he can be as proud as anybody for his outstanding contribution this afternoon.

The dream of finishing in the top four remains very possible for Slaven Bilic's side, who are now one place and one point behind fourth-placed Manchester City.
It was Payet - who also managed 104 touches, though his passing was slightly erratic - who scored the last-minute winner which has fans daring to dream about mixing it with Europe's elite clubs next season.
And what a first season it would be at the Olympic Stadium if they can achieve it.
