Roma striker Mirko Vucinic says scoring away at Arsenal is critical in their Champions League clash.
"I am optimistic that we can finish in fourth place this season," Vucinic told Sky Sport Italia.
"I don't know whether it will require five wins in a row or maybe 10 but I believe in finishing even higher than fourth.
"As for the Champions League, an away goal is very important in this competition.
"It will be difficult for us, but I am optimistic. I like the way Arsenal play with power and pace and Samir Nasri is very dangerous as is Robin Van Persie."
