We are paying Williams a reported 70k p/week.
Bolasie 90k.
Before that our current top earners were Lukaku (75k - will almost certainly get offered the new deal come September) and Baines (70k).
So quite clearly we are.
And you're again falling into the trap of 'offer him more money, that'll mean this player that is 27 playing for pretty average clubs all his career and has been offered the chance to go to Arsenal (one of the biggest clubs in the world) will chose us instead of them'.
Also, are you seriously suggesting we pay a striker who (while looking decent) has had one very good season but would be brought in primarily as back-up, 100k+?
