Napoli coach Walter Mazzarri insists he's happy with the progress of Natan.

The defender has battled for consistency in his first season in Serie A.

Mazzarri said: "Natan is doing what he could do so far, if he plays again I expect a greater push because I know that in Brazil he played in a four and was a full-back. But let's put ourselves in his shoes... When I was in Turin Bremer came and in the first four months he seemed like a different player compared to the defender we admired later.

"It's normal to pay a duty when you arrive from Brazil in a championship like ours. Zanoli can also play on the left, but he was injured and has less playing time. The fundamental thing is the solidity of the team."
