Ranieri signed Makelele.
Always had a lot of time for Quaresma, since players of his talent don't come around very often. His problem, however, is that he does not possess the strength of character to complement his talent. He failed in Barcelona, and he failed in Italy.
Keep in mind that just because its a loan deal does not mean that he didn't cost Chelsea anything - they probably still paid a nice fee to take him on loan.
