Stephan El Shaarawy has urged his Roma team-mates to maintain their superb run of form when they face Serie A high-flyers Inter Milan on Sunday.

Roma failed to win any of their first three games of the season and were thrashed 4-1 by Genoa at the end of September.

However, Jose Mourinho’s side have since won five games in a row in all competitions, scoring 13 goals and conceding just one in the process and are top of Europa League Group G with a 100 per cent record.

Asked if something had clicked following the defeat to Genoa, El Shaarawy told the club’s website: “No, it was something that defined us the past two years.

“We manage to work together in challenging situations. We unite and evaluate our mistakes to avoid repeating them.

“Our group has always been our biggest strength. We have done a good job of preparing for the games and what we needed to do in recent weeks, but there is still work to be done.

“The season is long and there will be a crucial encounter on Sunday. We must continue in this way.”

Roma will have their work cut out on Sunday however, Inter having started the Serie A season with seven wins, one draw and one defeat from their opening nine games.

Simone Inzaghi’s side have scored 24 goals and conceded just five for a goal difference of plus 19, the joint best in Europe’s top leagues along with Bayern Munich.

Roma striker Romelu Lukaku is set for a hostile reception as he faces his former club for the first time, despite Inter fans claiming they have been banned from handing out whistles to create a noisy return for the striker.

“Yet another abuse. Whistles prohibited,” the Curva Nord Milano group said on their Instagram page on Friday.

Mourinho, who won several trophies in his two seasons in charge of Inter, has tried to play down Lukaku’s return.

“I’m shocked by the whole thing because I didn’t think Romelu meant that much to a club with Inter’s history. It’s a surprise for me,” Mourinho said earlier this week.

The Portuguese coach will have to watch from the stands on Sunday as he is suspended following his red card at the end of Roma’s win over Monza.
