"He's a good centre-half, we could see that here, so I'm not surprised that he's doing well for Bolton," Laursen told the Birmingham Mail.
"He's strong, tall, good in the air, okay with the ball and I think he's got a good attitude as well which is important for him. I played alongside him a few times.''
Villa fans questioned the wisdom of allowing the England Under-21 international to leave to join a top-flight rival for around £5million in January.
"I think he was struggling to play here so if a Premier League club wants him and he can see that he's got better possibilities to play there than here then it was the right thing for him to do,'' said Laursen.
"You can see that now that it was the right thing for him to go elsewhere because he's playing and playing well, so it's good for him.
"We have very good centre-halves here so that's not a problem."
