I'd be interested to know how the contract offer compares with the rest of the squad.
I'm a big fan of Ross, but both Gana & Schneiderlin came in last season & showed real consistency & value to the team. Probably what Koeman calls productivity. They do their job, no fuss, nothing flash, minimal mistakes. On the other hand, Barkley does a few flash things, looks brilliant, but then too often loses the ball. Should Ross be paid more than Gana & Scneiderlin? I would say no.
The emergence of Tom Davies should be another reminder to him. He may not have some of Ross' abilities, but his work rate & intelligence, quick feet, I would say he was possibly showing more value to the team than Ross.
With Klaassen coming in too, I can totally understand the club's take-it-or-leave-it approach. IMHO, he should sign it & get his head down, get back on track. Everton are moving forward with or without him.
