Claudius We're already doing it in this position. You've noticed our left wing starter generally only plays an hour or 70 minutes tops.
When you factor in the step down on corners won and holding width if we loosen up the rigours of how Martinelli plays this role, we need to be looking at either near world class, or "Saliba" style recruitment at left wing.
We already have Trossard and Jesus as different top drawer "luxury" options who don't have quite the same mobility, stamina and work rate as Martinelli, but are elite when taking on defenders.
Nico Williams seems to fit the bill for us ... and Adingra who can allegedly play both sides is arguably a "Saliba" who could at least put an end to Fabio Vieira at squad level.
Meanwhile it'd be good to see Martinelli actually getting released in transition from time to time. Many excellent wingers would struggle to produce much against the compact and prepared defences we so often face.
