Bayern Munich winger Arjen Robben has launched a swift defence against allegations that he spat on Bacary Sagna during last night's 2-0 win over Arsenal at the Emirates, insisting that the video footage merely shows sweat dripping from his head. Robben sent social media into a frenzy following the Champions League last 16 clash after appearing to kneel down and send saliva in Sagna's direction while the Frenchman was down injured, on what was a very busy night for the Dutch international. With video footage of the incident far from clear German tabloid Bild asked Robben for clarification yesterday and were given short shrift, told by the wing wizard that he wouldn't bother coming home if found guilty of such a horrible offence.
