It doesn;t make them necessarily a great side, but he would really shake things up and force the others to step up their game. Maybe they could add yaya Toure as well. Eto'o if he finds the passion again will be a terrific signing for any club.
If they signed a good keeper and central defender they could really compete.
I'm not sure if King will be there next season and if he;s not, they need someone, because Dawson and Kaboul aren't up to par (yet).
