Mariners coach Alen Stajcic was keen to bring the 17-year-old on board and a firm offer was tabled.
There was even talk of Teague being fast-tracked into A-League calculations, subsequently denied by the Mariners.
The Mariners’ move for Teague - who will lead Australia into combat at November’s U-17 FIFA World Cup in Brazil - concentrated the minds of the Sky Blues hierarchy and a contract renewal was swiftly prepared to keep Teague in the Harbour City on scholarship terms for a second year.
From there lies the promise of a full professional deal should Teague continued his current upward arc.
Highly-rated by coach Steve Corica, Teague has improved exponentially since helping mastermind Australia’s qualification for Brazil at the AFC U-16 Championship in Malaysia last October.
The expectation is that he will train with the senior squad - whilst remaining a part of National Youth League set-up.
The 12-month deal opens the door for Teague - a budding number six renowned for his composure - to provide competition for senior midfielders like Brandon O’Neill, Anthony Caceres and Paulo Retre.
