The only reason Arteta is paid the highest at the club is that we desperately needed to keep hold of him. We're half the team without his influence in the centre of the park, and judging by his comments, after signing the new deal, his head was turning towards the exit door.
Apart from him, if the rumours are true then no one earns more than Moyes. Arteta is the only one because he's irreplaceable to us. Pienaar needs to accept that as the reason why Mikel earns more than Moyes (allegedly) and take the offer. He won't get much better than 60k a week here.
