QPR boss Ian Holloway says Steven Caulker and Ariel Borysiuk are like two new signings for the club.
Defender Caulker has returned to training, having recently spoken of his mental health issues and addictions to gambling and alcohol.
Holloway believes the former Tottenham man is on course to return to action for the R’s.
Speaking at a press conference, Holloway said: “I’m delighted to have him back. That is a potential England centre-half.
“He has only just been training with me. It was pretty well documented; his article in the newspaper was really open – as open as I’ve ever seen any footballer.
“Part of me was really sad about that, part of me was pleased and proud of him to actually admit that.
“Now he is in a fantastic place and he wants to come back and he wants to work and I can’t believe that I’m the lucky person who will get to work with him. The lads feel the same way.
“For me, now, it’s about helping him, to keep playing, keep working and keep improving.”
Polish midfielder Borysiuk was sent out on loan by Holloway after failing to impress him last season.
Now he too is back with the Rangers squad and Holloway likes what he has seen of him so far this summer.
“I’ve got Borysiuk back and he’s like a new signing for me. He’s fitter and healthier than he was last year. That’s a Polish international,” he said.
“I’m delighted with how he’s showing me how he wants to play for us. I didn’t really give him that chance last year, did I?”
