Head Coach Richard Hill said: "I have been delighted with Marcel during my time at the club and he fully deserves this award for a fantastic final season at the club.
"He has been one of the standout performers in the squad who is consistently impressive week in and week out for us. He has given his all every time he has pulled on the jersey. He remains one of the best wingers in the country in my eyes and leaves some big shoes to fill."
The Players' Player of the Year Award was claimed by uncompromising back row Sam Betty who has enjoyed a stunning debut season at the club and made 24 senior appearances. Fellow nominees for the award were Dale Rasmussen and Garvey.
England Under-20 back row Matt Kvesic claimed the Young Player of the Year for the second successive season ahead of impressive young prop James Currie.

The club's Community Award, for the player who has excelled with his commitment to the club's work off the field in the local area, was won by Shaun Perry. Fly half Andy Goode and Errie Claassens were also nominated.
