Jones is sad to see his former team rooted to the foot of the table but believes they can turn things around in the second half of the season.
The defender told United Review: "I’m still a massive fan – as soon as we come off the pitch I always look to see how Blackburn have got on. I still have a lot of friends at the club.
"I’m sure they’ll kick on and things will improve. They’re a lot better than their league position shows. Unfortunately, for whatever reason, they’re at the bottom of the table now.
"We won’t find it easy, though. It’s going to be tough. I know what sort of squad Blackburn have and there are some cracking players there. We can’t take them lightly."
Jones, who describes the experience of losing 7-1 with Blackburn at Old Trafford last season as "probably the worst day of my football career", is loving life with the Reds.
"Ever since I arrived I’ve been made to feel welcome," he said. "I’ve settled in quickly and I’m really enjoying my football, probably more so than ever before. I just hope I can continue at United for a very long time."
