AS Roma coach Jose Mourinho sees their double-header with Slavia Prague as decisive in their Europa League group.

Roma host Slavia tonight before going to Prague in fortnight.

Mourinho said: "There will be two matches with them where many things can be decided. We are both teams in a good position, but since we want to finish first, these two games become fundamental.

"It's difficult, they have an excellent team. If we let them play they know how to do it, they have lots of offensive options with five attacking players all potentially starting.

"It will be the 39th match sold out... We hope to reach 40. Tomorrow will be important, we have no chance of doing the turnover like other teams. The boys need help like they had on Sunday, when we didn't play well. In other stadiums the fans would not have had the same wonderful behaviour, they had an incredible importance."
