Wales manager Gary Speed has died at the age of just 42, the Football Association of Wales announced on Sunday.
Wilkinson stated: “He had so much to offer as a person and as a sportsman.
“I just find it unbelievable. I cannot start to try to understand what his family are going through.
“Gary had a lot of talent and that talent became his job. Footballers are subject to all the stress and strains of things that happen in life.
“I always tried to get to know my players very well. He was a star in the truest sense. For him at 42 to leave us is such a tragic loss. He had a life of success to look forward to.”
