Formerly with PSV, the 19-year-old midfielder also had a spell at RW Essen in Germany and arrives at Spurs straight from the Olympic Games in Athens, where he was the youngest member of Australia's squad.
Melbourne-born Spase has also represented Australia at both the World Under-17 Championships and the Under-20 World Cup.
"We're delighted to sign him," said Sporting Director Frank Arnesen. "Spase is a midfielder who has already played international football for Australia's youth teams. He also was the youngest member of the Australia squad at the Olympics. A player who will start in our reserves and we'll be looking for him to step up from there."
We are pleased to announce the signing of Australian youth international Spase Dilevski.
