"We've agreed a fee for Steven Caulker, who I like very much," he told Sky Sports News.
"I had him at Tottenham as a player and he's done very well. I think for him to come and play with Rio would be a great experience for him.
"I'm looking to play with three central defenders this year. So (there are) those two and then I've got Richard Dunne, Nedum Onuoha, Clint Hill, I've got real good defenders here.
"I think for Steven Caulker to come in and be part of it with those experienced players will be great for him.
"I think Rio will be a big influence on him. I think for Steven it will be the best education he could ever have in his life to play with Rio."
