Rovers boss Darrell Clarke swooped for Sweeney once again in the summer – on a season-long loan – and the centre-half says he didn't have to think twice about joining the club again.
“The manager is a massive reason why I came back this season," Sweeney told the Bristol Post.
“He's always demanding more, and I like that. It's why he has taken the club so far.
“He's a great manager. He still wants more out of us, and we know we can give a bit more in the performance."
