Roma are four points behind Inter ahead of their clash at the Olimpico in Rome.
Roma managed to beat Bologna 2-0 last night.
“We have done what we were expected to do so far and now a big battle awaits us,” Mexes told Sky Sport Italia after the match.
“We’ll wait for them at the Olimpico. It will be a big match. We are a more mature side compared to two years ago. There is strong belief and we are on form.
“We’ll try until the very end, as we have nothing to lose. We have been waiting for this game for five years. But we must not buckle under the pressure and play it with a cool head. It’s nice to hear the word Scudetto, it’s a wonderful dream…”
