He earns around 60.000/week gross.
Same rumours placing the likes of
N.Matic - 120k/week => ~5.7m/year
J.Lingard - 25k/week => ~1.2m/year
A.Martial - 65k/week => ~3.1m/year
J.Mata - 140k/week => ~6.7m/year
A.Valencia - 100k/week => ~4.8m/year
My point is that they seem accurate, they have to be net wage, think about it for a second, otherwise our wage bill here looks even the more ridiculous having the likes of Matuidi on 5m/year net, United are big spenders afterall, they have fricking Pogba on ~12m/year and the likes of Lukaku on 9.8m/year.
Ofc they might not all be real, but it's definitely closer to being net rather than gross at those numbers, EPL is renowned on paying absurd wages iirc.
