AS Roma boss Vincenzo Montella has concerns over Mirko Vucinic after their Coppa Italia defeat to Inter Milan.
Dejan Stankovic struck Inter's winner, but in the opening minutes Vucinic missed an open goal - something he also did in the 3-2 loss to Palermo.
"When things like that happen and you miss really easy goals, it's difficult to say anything," said Montella.
"Mirko did some good things and other less good things, but it's obvious he is under stress during this time.
"As for the team performance, people only tend to judge the result, whereas the difference can be made in a single incident."
