I laugh when Arsenal fans complains that Trossard is not a good player, but I still remember how many times Trossard has scored for Arsenal with the little minutes he has been playing for the team. They already have Martinelli and Trossard in that wing adding Rodrygo will be a disaster and unless they sell one of them but so far there's no news about Arsenal willing to sell any of them.
The main issue with Trossard lately has been his fitness level
[specifically endurance] while also becoming susceptible to different injuries
[unfortunately]... Martinelli has been underperforming for the past two seasons and I really don't think he's suitable for the LW position
[IMO, Arteta should rotate him with Gyökeres instead (Martinelli played well in that position before and at the start of Arteta's era)]. In other words, Rodrygo will get enough time
[if we sign him] on that LW position
[even with those two remaining in our club].
