Juventus goalkeeper Gianluigi Buffon has added his weight to early season predictions that the battle for Serie A supremacy will be a two-horse race betweeen the Turin giant and AS Roma.

Ahead of this weekend's visit to Atalanta, champion Juve remains unbeaten and Buffon has yet to concede a goal, but the 36-year-old has taken note of Roma's early season form.

Roma is also unbeaten after four games and a 5-1 Champions League rout of CSKA Moscow two weeks ago has only served to underline their credentials on the domestic front.
