Napoli coach Walter Mazzarri has criticised his side's attack, despite Saturday's 2-0 victory over Catania moving them level with Serie A leaders Juventus.

Marek Hamsik opened the scoring for Napoli in the 31st minute before his low cross gave Paolo Cannavaro an easy finish from close range as the Partenopei sealed the match before half-time.

But Mazzarri was left to rue a number of missed chances in the second half and has urged his players to become more instinctive in front of goal.

"I cannot change my attitude by looking at the table," he said. "Our results come from battles like the one we had today and we must not get distracted. We need to remember every game is a battle.

"We did well not to panic during some moments under pressure today, though we still need to mature in those terms.

"We should've killed it off with a third goal, even if at times the state of the pitch penalises us. If you want to win in modern football, your strikers have to work hard and help out when the opposition has the ball."

In Saturday's other game, Torino stretched their unbeaten run to seven matches but did little to set pulses racing in a listless 0-0 draw with Sampdoria at Stadio Olimpico.

The hosts impressed in a 2-2 draw at Inter Milan last time out but little of that fight was on display, as they were cancelled out by a Samp side also on a high following last week's 6-0 win over Pescara. The result does little for either side's bid to haul themselves out of mid-table obscurity.
