Inter proved they have what it takes to maintain a serious title challenge this season by defeating reigning champions Juventus 2-0, according to Arturo Vidal.
Vidal opened the scoring against his former club at San Siro on Sunday, heading home a cross from Nicolo Barella to find the net in Serie A for the first time since his goal clinched the Scudetto for Juve in May 2015.
He became the first ex-Juve player to score for Inter in the Derby d'Italia since Christian Vieri in 2004 and the eighth player to score for both sides in the fixture.
