Chelsea boss Ancelotti backing Roma for Scudetto
Speaking to Radio anch'io lo sport, Ancelotti said: "It's surprising that Roma have overtaken Inter. It has been an extraordinary season with Ranieri who has done things that no one expected.
"The Giallorossi haven't missed a beat, it has been a run of great quality.
"Now comes the difficult part because keeping the lead at the top of the table with only a one-point advantage is not at all easy.
