5) Yaya Toure/Ross Barkley (Manchester City)
With Manchester City keen to sign homegrown players this summer, Everton wonderkid Ross Barkley is one who has caught their eye and who could be a superb long-term buy for the club. The England international would fit in well alongside a number of technical players at City, and could really learn from playing alongside someone like Yaya Toure, who has been one of the best in the world in the position for so many years.
