Real Madrid legend Fernando Hierro has said that Manchester United's Phil Jones can be world class.
Hierro has since described the defender as a "great talent".
"I know Jones very well," he said. "He played for England against Spain last summer in the Under-21 European Championship and was very impressive.
"I was there and said that England had a serious talent. Sir Alex Ferguson would not pay so much for him if Jones was not a great talent.
"If he keeps evolving the way he is he will be world class."
The former Blackburn man joined the Red Devils for £16.5m earlier this summer.
