Inter Milan matchwinner Hakan Calhanoglu was tightlipped over Romelu Lukaku's return with Roma this weekend.
Calhanoglu, voted best afield, struck from the spot as Inter won their Champions League clash with RB Salzburg 2-1.
He later said: "It wasn't easy but we knew it, they are a young team that runs a lot and has enthusiasm. It was important to win, now we are first and we will play the next ones away from home.
"We know how to react immediately when we want to. We have to play with mentality and intelligence, playing every 3 days is never easy. We did well and deserved to win."
On Lukaku's return to San Siro, Calhanoglu added: "I don't want to comment on these things, everyone makes their own choices. We focus on our work, we are first in the standings and we want to continue like this."
