The Giallorossi surrendered top spot to Inter last weekend after a 2-1 home defeat by Sampdoria.
Inter now boast a two-point lead with just three games remaining until the end of the season, but Toni remains upbeat.
“We have digested Sunday’s loss and now must concentrate on our upcoming games,” the Italian international striker writes on his official website.
“We have to give our best in these final three games, starting with the Parma clash. Meanwhile, let’s wait and see if Inter perhaps falter…”
Roma will pay visit to Parma at the Tardini on Saturday while Inter play Lazio in Rome on Sunday night.
