It's a very small thing but the RW has to be left footed in my opinion & personally would not be too happy with a winger who prefers his right foot even if capable of using his left.
It's just something that I feel is essential to getting the front 3 working.
We have martial being a player who prefers cutting in rather than taking on the RB from the outside. We have Rashford who is right footed; again likes cutting in when he finds himself on the left side of the pitch whilst on the right hs takes his players on more on the outside like a traditional winger.
I'd really want to see a left footed forward in that position. It's personally why I think Greenwood has a bigger chance of breaking in to that spot than anyone else. Ideally we could try break him in ASAP so we can see if he is ready to make the step up or not first.
Either way - Left footed is a must.
ESPN has United paying 50m pounds for Ryan Sessegnon. According to Transfermarkt, Sessegnon has 1 goal and 2 assists in 270 minutes at RW vs Spurs, Cardiff, and Arsenal this season, his best production per match in any position in the EPL. Maybe Ole see's something there.
I didn't know this guy was left footed so maybe he could play RW for us whilst using that left foot to attack.
However, I've not been all that in awe over his attacking abilities this season & as young or new to the position he maybe - he still seems like he has a further bit to go to properly become a consistent attacker that is relative to his age.
Considering Martial is looking like our long term left sided attacker & he tends to cut in - using sessegnon as a LWB that provides width is much more in line with where I see him long term.
