Bennett sensationally signed with the Rabbitohs despite having a year to run on his deal at Red Hill, effectively switching places with incoming Souths coach Anthony Seibold.
“I’ve spoken to South Sydney … I have a responsibility here,” Bennett said.
“Players, staff that I work with, the fans, I felt I’d be letting them down if I went a year before I should.
“There’s a lot of things going on behind the scenes there.”
Bennett said his contract situation was not causing dramas at the club.
“The drama hasn’t been me. The drama has been everybody else. It’s never come from me.
“Today the deadline for me was because the speculation was mounting and I was going back to training on Monday.”
The seven-time premiership coach also praised South Sydney for orchestrating the deal and is keen to take over their top job in 2020.
“They’ve been outstanding South Sydney. Richo came to England to see me to talk about the contract … I’m disappointed for them but I’ll be there in 2020
“I have no problems about next year and how I’ll handle it. It’s not an issue for me.”
“I did it here in 2008 … I’m ready to coach.”
The clubs have set themselves a deadline until 5pm today for the coaches to swap places, and with a deal not being reached, Broncos powerbrokers will now decide whether to sack Bennett.
