Geyer said while he would feel for the Bulldogs, if they miss their man but "for his own personal sake I think where he is, is best for him".
Foran's children live in Sydney and it had been assumed he would head back to Sydney at the end of this season. However, there are suggestions Foran is happy at the Warriors and may be rethinking plans to return across the Tasman.
"I don't know that situation [Foran's children]. I'm talking purely about rugby league," hardman Geyer said.
"It's like he never stopped playing rugby league [for] that 12 months.
"He's an unbelievable player and being over in New Zealand is where he should be if he wants to go better and better."
Foran missed last season with injuries and has worked his way back from off field issues.
"I don't want to talk about the personal side," Johns said.
''From a football point of view, if he was to sign a three-year contract with the Warriors I believe in that three years they'll win a competition.
"He makes that much of a difference and I reckon [the Warriors] are just one high-class forward away from winning the competition."
