Inter Milan coach Luciano Spalletti says they must play to win against Napoli.
Inter are unbeaten so far in head-to-head clashes with the other top teams, drawing at the Stadio San Paolo earlier this season.
Spalletti said: “We don't give anything more in these fixtures, but probably the players feel more responsibility and awareness of what they need to deliver at this level. That shouldn't happen from one game to another, but involuntarily it can do.
“In Naples we played a bit too deep and ran too many risks, which we must avoid doing tomorrow. We needed to spread Napoli's defence, but instead tended to cut back inside at the crucial moment.
“I wouldn't settle for a draw tomorrow, because being afraid of defeat is not a strategy. You can get a draw, but only after trying everything to win the game.
“We mustn't get stretched out beyond 30 metres, because Napoli can juggle the ball at their feet and take advantage of any spaces. They play pleasant and impressive football, matching it with results."
