After victory over Sampdoria, Napoli remain in the top four.

German Denis struck the only goal of the game and Napoli coach Walter Mazzarri admits he's reluctant to make predictions.

He said: "We can only have a verdict on our campaign at the end. It is a very balanced Serie A and details make the difference, so we must work on the little things rather than set ourselves huge objectives.

"This is the right attitude if we want to keep on getting results. It was good to see German score and that just confirms the strength in depth we have here."
