Bitter rivals Lazio are the favourites to take the fourth and final Champions League qualifying spot in the league, according to Roma's Marco Cassetti. Lazio currently hold fourth place by one point from Udinese, with Roma a further three points back in sixth with just four games remaining. And as much as it would hurt Roma to miss out to their neighbours, Cassetti admits that's a very realistic possibility. "The favourites for the last Champions League place are Lazio, they're fourth and their destiny is in their own hands," he said on Thursday. "But Udinese won't be beaten easily. Even so, we'll try, we'll try to win all our remaining games and hope the others slip up." And in a difficult season that saw Roma change coach at the end of February and crash out of the Champions League 6-2 on aggregate against Shakhtar Donetsk a couple of weeks later, Cassetti admitted he has regrets. "We have many, no-one was expecting such an inconsistent season. These things happen but we hope to end on a high."
