"It's a real honour to win this award, but it was only made possible by a great team performance to knock out a very good Newcastle side," said Cheyrou.
"I also want to thank all the Liverpool fans who took the time to vote for me on the FA website."
Cheyrou won 55% of the impressive 230,000 votes recorded on the FA Cup website, which nominates Arsenal wonderkid Jose Antonio Reyes, Tranmere striker Iain Hulme and Manchester United shot-stopper Tim Howard for the fifth round accolade.
