Young pitch invader busted after Barcelona FC's win over A-League side

A cheeky pitch invader has memories he will cherish for life after 'storming' the field moments after FC Barcelona beat the A-League All Stars 3-2 in Sydney on Wednesday night.

The starry-eyed youngster headed straight to Barca head coach Xavi Hernandez, who no doubt was relieved the Catalan football giants escaped with a win in the five-goal thriller at Accor Stadium in front of 70,174 fans.

On the pitch, the crowd were treated to an entertaining 90-minute spectacle, with  French star Ousmane Dembele opening the scoring in the first half with a clinical finish.

Incredibly, the Dwight Yorke-coached locals took a 2-1 lead after halftime, thanks to goals from Reno Piscopo and Adama Traore.

With bragging rights on the line, the La Liga runners-up lifted the intensity, with hulking winger Adama Traore and wonderboy Ansu Fati, 19, finding the back of the net.

Former Manchester United striker Yorke, who had just two days to work with his squad of home grown talent, was left pondering what might have been at the final whistle.
