Richarlison
Not an out and out forward, but the Brazilian could help to solve a problem on the right-hand side of the front three. Neither Dan James nor Mason Greenwood see it as their favoured position while the Everton man plays his best football there.
Richarlison is still only 22, and while he is a streaky player, he would add goals to the team. This campaign, the forward has scored eight goals in 24 games.
