We are prioritising the likes of Young, Smalling, Jones, Martial. But Herrera is allow to run down to the point that PSG can offer a wage that's high....because there's no transfer fee.
Herrera getting a contract 18 months ago and he likely goes from ~70k per week to 120k per week.
On top of that, you have the likes of Martial getting a payday for no reason. Then he sulks on the pitch. Herrera was out there leading the troops, praising sanchez in the press to help with confidence. Doing all the captain things.
So why do we "draw the line" at Herrera, but the rest of the trash get a free pass?
