Liverpool boss Jurgen Klopp admits he's a big fan of Arsenal striker Gabriel Martinelli.

The 18-year-old, who joined the Gunners from Ituano over the summer, scored twice during Wednesday's 5-5 draw as the Reds won on penalties book a quarter-final meeting with Aston Villa.

Klopp, who made 11 changes for the tie and handed to starts to several Liverpool youngsters, was full of the praise for Martinelli as he paid tribute to the contributions of some of his younger players.

“Sepp van den Berg played an incredible game," the Reds' boss told Liverpoolfc.com.

“That's really difficult to deal with these guys. Martinelli's pretty much the same age but he's a talent of the century, he's an incredible striker, so it's really difficult.

“Then you have Mesut Ozil around and Willock right, who scored by the way a really nice one, so a team like Arsenal in a counter-attacking mood – we keep them deep, play around them, we lose the ball and then it's really difficult."
