I'd argue otherwise, we paid a large loan fee for Barry and then have paid him very well. He's had a terrible discipline record missing numerous games over his time here through suspensions, he's also made numerous high profile errors in big games that people love to wash over (Arsenal QF, Anfield Derby 13/14, even last weekend v Leicester). McCarthy and Barry get so much praise yet have been ever presents in probably the laziest, least bothered, biggest bottling, Everton side in premier league history who have been regularly caned humiliatingly by better sides.
In truth they were two extremely average prem midfielders, one who had been good but we got him past his best so had one decent season (why have we given him another contract ffs), the other was never good enough, we overpaid on him.
It is absolutely no surprise to me whatsoever that two of the first buys through the door have been players to replace these two. People wonder why we dropped from top 7 to bottom half under Martinez, look no further than replacing genuine top 6 players like Cahill Arteta Pienaar Fellaini with average dross like Cleverley Barry McCarthy.
