A Valencia fan has been caught on camera appearing spitting in the direction of Pierre-Emerick Aubameyang as he celebrated scoring from Arsenal.
BT Sport cameras captured the supporter's disgusting reaction to the Arsenal players congratulating the Gabonese forward on netting a stunning hat-trick on Thursday night.
The Gunners went into their Europa League semi-final in Spain with a two goal buffer from the first leg, after they beat Valencia 3-1 at the Emirates.
A hat-trick from Aubameyang and a goal from Alexandre Lacazette ensured the north London club will be playing in the final in Baku in June, despite two strikes from Kevin Gameiro.

"I am very proud of the players and the supporters," said Arsenal boss Unai Emery after the match. "The players did all they could and we can be proud of the whole club."
Emery has won the tournament three times with Sevilla.
He added: "The past is for experience and can be used in the present. It is very difficult to play in finals and we took our opportunity today which we are happy about.

"We knew we had to be calm after they scored and we needed to control our emotions.
"It is very difficult to score four goals against this team because they are very organised. It gave us confidence to score quickly we know our strikers are taking chances."
