I think so
Others will say 4-3-3
But imo son was playing left wing first half
It's a bit of a wonky formation imv
------------Son Kane Richarlson
-----------Hojberg Skipp Porro
Davies Lenglet Romero Royal
With Davies pushing up more than Royal and Son dropping back more than Richarlson.
It's almost like we're trying to play to our players strengths
