I typed out a list, then realised it was exactly this.
Hard to exclude Costa, on his day can bully any defence. But those 5 are truly World Class without a shadow.
Hazard ahead of Alexis? Lol wut?
This season: Costa, Alexis, Mane, Ibrahimovic, De Bruyne.
Generally: Agüero, Hazard, Özil, De Bruyne, Alexis.
