Mikel Merino will rightly get plaudits for his double in the 3-0 victory in Prague and that defence might be deservedly being praised for breaking records.
But in an Arsenal team which has suffered its fair share of injuries this season already, a diminutive Belgian wide-forward has emerged as a real unsung hero.
Leandro Trossard was expected by most Arsenal fans – myself included – to be a bit-part player this season.
Many assumed the arrival of Eberechi Eze and Noni Madueke could force his exit this summer. But here we all are in November, with a quarter of the season gone, and he has himself three goals and four assists in 13 appearances for the Arsenal.
The cross for Merino’s first goal last night was absolutely inch perfect and while Merino still had to time his run and get the finish right, Trossard’s work certainly helped him make it look as easy as he did.
There were times last season when we were decimated with injuries that his form slipped and we could not wait to see the return of Gabriel Martinelli.
Indeed, this season with some of the goals and the form that Martinelli has shown, I thought Trossard would find his place back on the bench eventually.
But even a few weeks back when Martinelli was available to start, Mikel Arteta still preferred starting Leo, and I can see why.
He had the beating of his man last night and seems to have picked up half a yard of pace too this season, despite being 30 and one of the elder statesmen in the team.
We all know his close control and ability to change direction gives him half-a-yard advantage at times, but it feels like he is using it even more effectively than he has previously in his Arsenal career, which is timely given all the injuries the attack has.
At a time in which we lost another one in Viktor Gyokeres last weekend, Trossard gives us hope of end product at Sunderland.
