Roma keeper Alexander Doni has warned Manchester United that they will be punished if they get complacent.
The Brazilian will line up for the Italian giants at Old Trafford on Wednesday knowing that his side have a two-goal deficit to overturn from the first leg of their UEFA Champions League quarter-final.
That defeat in Stadio Olimpico last week means that United are now red-hot favourites to progress to the last four, but Doni is hoping that the Premier League leaders will take their foot off the gas during the second encounter.
"They are leading 2-0 so maybe that will make them relax too much," he said.
"Perhaps they will be complacent and not have the intensity that they need. That is our hope.
"The biggest chance we have is that United will think they are already through."
