Deployed in central midfield and the England international thrived with the responsibility.
Good in possession, most illustrated by his assist for Welbeck's second, energetic in his work offensively and defensively and much more disclipined than he can be at times.
Arsene Wenger made 10 changes to his side but it was still packed with experience and quality, far more than Southampton.
The likes of Mesut Ozil, Petr Cech, Laurent Koscielny were left at home.
So with a fully fit squad, Arsenal should be capable of mounting a sustained challenge in the closing months.
