Your teams are evenly matched, in terms of overall squad and starting 11. In many cases, possession is cosmetic, but it could also be your V formation getting overwhelmed by his 5-4-1. He can bypass your DMC by playing the wings, so your DMC in this case is useless. His MCs was probably on form so they matched up evenly with yours.

Just forget this and move on. It happens. Nothing is for sure.
