Napoli coach Walter Mazzarri is confident of a busy summer market.

It's believed he only agreed to remain at the San Paolo if the squad reinforced considerably for the Champions League.

Mazzarri said: "We have grown remarkably and the objective is to continue improving by doing well in Serie A and honouring the Champions League.

"You know that the Coach gives suggestions to his club and we will make three or four signings. I am sure Marek Hamsik and Ezequiel Lavezzi have no reason to leave Napoli, especially now we are in the Champions League."
