Barry - Agreed, a good signing
McCarthy - good first season, average since. At his best, worth the £12M we paid, but I doubt if he'd get into any team challenging for a CL place.
rodriguez - never seen him so probs crap agreed
hennen - see above
lukaku - a good signing, agreed, though on his last 2 months' form he was useless.
Gerry - promising, but for some reason can't play 90 minutes. If her gets fit he may be worth having.
Kone - Utterly useless, a very few good games, other than that three wasted seasons. Martinez deserves sacking for this buy alone.
Alcaraz - Not worth the money (I know he was free, btw)
McGeady - can't get into Sheffield Wednesday's squad. That says it all.
Niasse - *shakes head*
Funes Mori - Worth keeping
Mo Besic - Injury prone hothead who can't get a place in a struggling Everton team.
Joel - Has made too many absolute howlers to be anything other than a back-up.
Lancia Traore - what a bargain he turned out to be!
Cleverly - a good free transfer, but nothing more than a squad member.
Martinez's transfer record was mainly poor. I can't think we'd recoup what we paid on any of them bar Lukaku, and maybe Mori.
....looking at this, I suggest his transfer dealings would show a profit if those still at the club were moved on.
