The 64-year-old endured a difficult 191-day reign at Anfield which resulted in his departure in January 2011 after a run of poor results.
“Roy is a good manager. I’ve worked with him before but I think he took the Liverpool job at the wrong time,” said the 31-year-old.
“My opinion of him has not changed before he got the (Liverpool) job, while he had the job and after it.
“He was very good technically, very thorough, a great guy and very loyal among the players. I think he is a good appointment.
Roy will be judged on results so we will see how it goes, but I am certainly looking forward to working with him again.”
