God help the league if they click during pre-season.Not sure about that: Sancho's greatest attribute (imo), beyond his skills and technical ability is how quickly he sees the pitch, reads and reacts to the opposition and his team-mates and pings off them like he's sending sonar - as long as he's interacting with players who have good-excellent one and two touch themselves and a quick enough mind to see the potential of the play that can unfold, Sancho and whoever it is won't get in each other's way, but will instead use each other as foils and dummies.
I'm expecting Fernandes to be in his element pinging balls into, and receiving balls, from Sancho. Same goes for Martial.
It's just imperative they get a good pre-season in to iron out the kinks and get a feel for each other's movements and preferences.
At the very least, it's going to be nice having three players up front who at any given time will need double-teaming.
