Lazio boss Edy Reja has dismissed the achievements of Walter Mazzarri at Napoli.
Reja helped Napoli earn promotion through the divisions up to Serie A.
He said: "(Aurelio) De Laurentiis didn't manage to get great results neither immediately after my sacking nor the following season despite having had time to shape the team.
"Mazzarri is doing well, but between his Napoli and mine there is a difference of 50m in investment.
"If I'd had that devil Edinson Cavani, I would have been top of the table."
