Speedster we don’t have particularly good , or quite often any, movement, ahead of the ball. Too many wanting ball to feet and not wanting to find space or run into it. Martinelli can do it a bit where the games more often, but I don’t think he’s got the nous to find the space in congested games even if willing. Havertz can be good, as can Merino b it neither appear to be nailed on starters next season. In general we don’t have enough players looking to get into awkward spaces for defences.
