Melbourne Victory goalkeeper and Joe Marston medallist Lawrence Thomas is among three Championship-winning players to commit to the club by signing contract extensions.



Also returning to the club for Season 14 of the Hyundai A-League will be stalwarts Carl Valeri and Leigh Broxham - both of whom played pivotal roles in Melbourne Victory's Grand Final triumph over the Newcastle Jets earlier this month.



Thomas, who delivered one of the great individual Grand Final performances to secure the Joe Marston Medal, has signed a two-year deal that will take him though until the conclusion of the 2019/20 season, while the experienced duo of Valeri and Broxham have each penned one-year extensions.



"In Carl, Leigh and Lawrence we have somewhere near 500 games of experience [for Melbourne Victory], so it was important to keep them at the club," said Victory Head Coach Kevin Muscat.



"All three contributed heavily to our success last season and with the added demands of another Champions League campaign ahead of us, they'll no doubt prove invaluable through both competitions again.



"We've still got a number of players to sign ahead of next season and there will be a period of adjustment required for most of those, so having leaders like Carl and Leigh in the change room is extremely important."
