Dai Young hailed young gun Leigh Halfpenny following Cardiff Blues' 58-0 rout of Connacht.
Wales Under-20 star Halfpenny grabbed a quick-fire double as the Blues ran in nine unanswered tries at the Arms Park.
And Blues coach Young reckons Halfpenny, 19, is ready to set Europe alight next month.
Young said: "Leigh was outstanding and thoroughly deserved his man-of-the-match award. He was the leading light for the Under-20's last summer and is a quality player.
"He really gets the supporters on the edge of their seats and could be a big surprise to other sides in the next month especially in Europe."
Fly-half Ceri Sweeney scored two tries in an impressive 21-point tally while Jamie Roberts, Rhys Thomas, Gareth Thomas, Ma'ama Molitika and Taufa'ao Filise also touched down.
Young added: "We were excellent and our quality really shone through in the first half. The forwards set up the platform and the backs were clinical - we're building momentum at the right time."
