Gallen and Bird formed one of the league’s fiercest forward duos before their partnership was dissolved in 2008 after the off-field controversy that forced Bird out of the club.
The pair were reunited during this year’s Origin series and even presented each other with their jerseys for one of the matches.
“I would love to see him come back and play here for Cronulla to be honest,” Gallen said. “I personally think he wants to come back and I’d love to see him back here.
“… I don’t know how many times I’m down at Cronulla or somewhere – and especially after Origin when we played together – how many people say ‘get him back, we want him back’. I think the whole Shire would accept him back for sure and I’d like to think the club would too.
“We could certainly do with a player like him and I think he’d like to come back.”
