Just an opinion, but Barkley and his agent obviously had a gameplan that has gone to pot. Whatever the reason, Koeman criticising, in that case he'll make it nowhere, moody ninjas, he'll be a repeat offender at any place, or genuinely thinks he could do well at another big club, see first two points, he has royally gnarlsed his career.
I suspect he's shot his bolt at Everton and is on 'gardening leave', club can't say that, PFA go all namby pamby on it, no one is interested in him at an appropriate price and the injury to whatever extent has been padded out to explain his non involvement.
We'd all like once in a blue moon to see a club letting a player rot his contract down for being disrespectful. Koeman obviously wants things done his own way, and I'm happy with that, Ross goes a little snowflake and pays the price, he was told sign or we sell, so him and his agent knew the situation. He needs a new agent.
I cannot see any future for him at Everton whatsoever, the great shame is he would have benefitted so much from the players that have been brought in. His big loss.
I think he'll go off the rails a bit...
