Arsenal suffered disappointment in the Champions League last night, with goals from Toni Kroos and Thomas Muller securing Bayern Munich a comfortable 2-0 win for Bayern Munich in the first-leg of their Champions League last 16 clash at the Emirates Stadium.
It all started so well for the Gunners, with Arsene Wenger's men making an assured start and even winning an early penalty through Mesut Ozil - which the German subsequently saw saved by compatriot and friend Manuel Neuer.
Belief quickly turned to gloom for Arsenal, however, as Wojciech Szczesny gave away a penalty of his own and was subsequently sent off for a foul on Arjen Robben.
Arsenal boss Wenger was evidently not impressed with Robben and the Dutchman was at the centre of more controversy later as the above video emerged that appeared to show that Robben could have spat on defender Bacary Sagna.
As you can see, Sagna was down hurt and as Robben bends down over him, a drop falls onto the back of his head. It has been suggested by many that it is simply a bead of sweat.
Is it spit or simply innocent sweat? Have a watch and let us know below - with thanks to The Metro for bringing it to our attention.
