the overload is created by their rw being able to double up due to doyle then stading at lcb - ego the place where we have more players than them unless they are playing 3 strikers would be at cb as we would have 3 cb's then against 1 or 2 strikers
If we saw him as a 6 who played a HB role where he starts as a CDM and can step back to make it a 3 in possession allowing both fullbacks to stay high while offering a bit more cover at the back.
Could work, he has the pass range.
