Spain set to see best of Diego Costa, insists Cazorla

The Brazil-born striker has struggled to find his best form for the reigning European champions but his confidence remains sky high, according to the Arsenal star Santi Cazorla insists Diego Costa is ready to fire Spain to the brink of Euro 2016 qualification, despite his sluggish start to the new Premier League season. The reigning European champions face Slovakia in Oviedo on Saturday hoping to regain top spot in Group C and avenge their defeat in Zilina last October.
