Ehh, I do think you're somewhat over-simplifying things here by calling Trossard, Martinelli and Eze "3 right-footed cut-inside and shoot merchants".
For some reason, the image quality from Scout Lab has turned out pretty horrendously when I've tried to copy them across here but I do think these do quite a nice job of showcasing the differences in how they play. In each image, a mark indicates an instance during the 2025/26 season where a player has attempted a take-on and where on the pitch the take-on was attempted. Green stars indicate that it was successful, red crosses that it wasn't. Teams are assumed to attack from left-to-right.
First, here's
Trossard:
Now
Eze:
Finally,
Martinelli:
I think from these images it's quite evident that, of the three, Trossard is the wide-player who "stretches the play" the most for Arsenal. His take-ons are concentrated in the wide areas, demonstrating that he sticks to the left-flank and commits the opposition's right-side to either leave him free out wide or stretch themselves to close him down. Eze seems to cut in earlier on a much more routine basis, which is entirely consistent with what you see from him when you watch him play for Arsenal. I am aware his map will be skewed by the fact that Arteta sometimes uses him as an attacking midfielder anyway but the point stands, I think, that he doesn't stretch the play nearly as much as Trossard. Martinelli, meanwhile, completes much more of his take-ons near the centre of the opposition box. This is again consistent with what I'd expect just from watching him; of the three players he's by far the most like a "wide forward".
The reason I bring all of this up is that it touches on a point of discussion you and I had in a different thread where I expressed my reservations about signing Rogers, despite thinking he's a fantastic player. If I know put the same maps of Rogers and Cunha side-by-side:
Cunha:
Rogers:
I think these show that neither Rogers nor Cunha will "stretch the play", if that makes sense. Both of their maps are most similar in profile to that of Eze's from the Arsenal examples. My point of view is that United would probably benefit from bringing in a wide player more in the Trossard mould on the left, since in matches where the opposition are able to effectively congest the centre I think it can be very handy to have a wide player who will stretch the play by sticking to their flank and beating players out wide with consistency. Doku at City is perhaps the best example of this in the Premier League that I can think of. Whilst his raw output isn't always that impressive, I doubt you'd find many City fans arguing that he's not an extremely valuable asset to their attack given the trouble he causes opposition full-backs. I'm not quite sure Rogers has that in his game, and since Cunha also doesn't offer it consistently out left it is something I'd ideally like to add to our left-flank this summer if we do make a signing there. If you weren't tired enough of them already - I've provided
Doku's map below as well for reference. The volume of take-ons he makes, and completes, from wide areas is just freakish.
