Serse Cosmi has called on Roma to support Jose Mourinho in the transfer market.

The Italian coach says Mourinho can turn Roma into contenders - if he's given the right players.

Fresh from coaching in Croatia with Rijeka, Cosmi told La Gazzetta dello Sport: "It drives me crazy.

"I say there are three super players there: Paulo Dybala, Chris Smalling and Nemanja Matic. If they add three others of that level to these, then we'll have fun.

"Mourinho is unique: if you give him good players, he wins."
