Roma coach Jose Mourinho admits he sees tonight's Europa League clash with Servette as a must-win.
Mourinho, however, says they'll have to overcome the Swiss pitch.
He said: : "I want the three points, away games are always difficult, the pitch is horrible and they are fine.
"They have never lost after the first leg match in Rome and are close to fighting for the title. If we win this one, then we'll play it all down to the last one.
"I grew up in teams like Inter, Chelsea, Real where it is impossible to make these types of choices (competition importance). We get to the end of the season and then if we absolutely need to make a choice then we will make it, but now I can't.
"There are still too many games left, this one is tough and it will be tough against Sassuolo too. These three days will be hard."
