Costa appears to lash out in Spain's draw with Italy
Diego Costa was again at the heart of controversy after he appeared to strike defender Leonardo Bonucci in the face during Spain's 1-1 draw with Italy in Turin.
In a replay of their Euro 2016 last 16 clash, Spain looked to have the match wrapped up after Vitolo capitalised on a Gianluigi Buffon mistake to slot home in the 55th minute.
However, Sergio Ramos hauled down Eder with eight minutes to go, allowing Daniele de Rossi to coolly slot home for a share of the spoils.
But the headlines were taken by Costa after his clash with Bonucci. The Chelsea striker was fortunate not to be sent off anyway when, on a yellow card, he kicked the ball away after conceding a free-kick - a decision that led to his hasty withdrawal by coach Julien Lopetegui.
In Wales and the Republic of Ireland's group, Serbia notched an expected 3-0 win in Moldova with Chelsea's Branislav Ivanovic and Southampton's Dustin Tadic both on the scoresheet.
Elsewhere, Kosovo are still looking for their first points as a footballing nation following their 6-0 loss to Croatia.
Mario Mandzukic netted a hat-trick for the Croatians, who eased to victory over the Group I minnows.
Iceland scored twice in injury-time to record a 3-2 win over Finland in Group I, with Ragnar Sigurdsson's 95th-minute strike proving the difference.
Turkey and Ukraine shared the spoils with a 2-2 draw, Israel won 2-1 away at Macedonia and Albania defeated Liechtenstein 2-0.
