Francesco Totti is confident Roma can inflict defeat on Shakhtar Donetsk and qualify for the Quarter-Finals of the Champions League.
Roma travel to the Donbas Arena knowing that they have to score twice in order to overturn the 3-2 deficit they incurred during the first leg last month.
"We know the formation well," Totti said. "We know the movements and the plays that we have to make and we will put Shakhtar in difficulty.
"They are two very important games. But first we must think about Tuesday's match then from Wednesday we'll think about the derby.
"I would like to play in them both, but if I have to choose one, I would say the derby also because I haven't played in one this season.
"Vincenzo Montella has changed the system. We have gone back to a tactic that we know well. The derby is important but for now we are putting it to one side."
