Juventus won a record-extending seventh straight Serie A title on Sunday after its 0-0 draw against 10-man Roma was enough to secure the trophy with a match to spare.

Second-place Napoli won 2-0 at Sampdoria but Juventus recorded the point it needed at the Stadio Olimpico to win the title.

It also completed a fourth successive league and cup double for Juventus, which had beaten AC Milan 4-0 in the Italian Cup in the same stadium on Wednesday.

Roma, which had already qualified for the Champions League, had the better of the game's few chances but its prospects of winning the match diminished when midfielder Radja Nainggolan was sent off 22 minutes from time following a second yellow card.
