He has the versatility to play both as a midfielder and defender so he'd be good for the squad.
The other sides currently linked are Liverpool, West Ham, Watford, and Leicester. At West Ham, he could probably beat out Jenkinson, who gets into good attacking positions but isn't much of a defender. He could probably displace Nyom at Watford and Simpson at Leicester but both of those teams rely on being solid defensively and he probably isn't at the level they need yet (Leicester were conceding like crazy with the more attack-minded De Laet in the back four). He'd be a loon to go to Liverpool unless he wants to cash in at 22.
None of those situations are significantly better than Everton. Maybe West Ham, but one has to factor in their record of general lunacy and the fact that sign six or seven players every summer even when they don't need them. We've improved the careers of almost every talented youngster we've signed recently -- our track record speaks for itself.
