Roma coach Claudio Ranieri rates Parma the hottest team in Serie A.

The two clubs face-off later today.

Ranieri said: "It will be even tougher than against Sampdoria. I have already warned the players it won't be easy and they'll need the right level of tension to get a result.

"Parma are the form team in Serie A right now, creating a mix of experienced players and youngsters eager to make their mark.

"There is also an excellent Coach in the form of Francesco Guidolin, whose sides always stop opponents playing at their best and cause a lot of problems."
