Fiorentina coach Cesare Prandelli is demanding an aggressive push from his players tonight against Champions League opponents Sporting Lisbon.

Sporting come to Florence after drawing 2-2 in the first-leg and Prandelli says: "We must not let them move the ball around, we cannot be passive, so I want to see the right mentality and aggressive approach.

"Sporting have more experience than we do, so I want to see a Fiorentina side that is sharper than recent outings."

He added: "It is crucial that we get through to the next phase of the Champions League. The worst thing we could do would be to defend the first leg result.

"We were in the competition last season and therefore have that decisive extra confidence in our abilities. I think we only need a slight improvement to achieve great results."
