Lazio president Claudio Lotito has ruled out coach Delio Rossi having more say on player signings and management.

"Since becoming president, I launched the idea to focus on young, affordable players for the club. Lazio is the first Italian company listed on the stock exchange and the fact that you have a coach who will also act as a manager is not allowed," said Lotito.

"This assumes that the coach has corporate knowledge. The coach must do the coaching and the president is the president."
