Manchester United boss Ole Gunnar Solskjaer has paid tribute to "incredible human being" Peter Whittingham following the former Cardiff City midfielder's death at the age of 35.
Cardiff confirmed on Thursday that Whittingham had passed away after reportedly suffering head injuries in an accidental fall last week.
Whittingham represented Aston Villa, Burnley, Derby County and Blackburn Rovers during a 15-year playing career but was best associated for his decade at Cardiff.
Solskjaer, who spent nearly nine months working with the Villa academy product in south Wales, told United's official website: "I was deeply saddened to hear of the passing of Peter Whittingham.
"Peter was a fantastic footballer and an incredible human being. I thoroughly enjoyed working with him during my time at Cardiff City.
"It's hard to believe that he has been taken from us at such a young age. Peter will be deeply missed and our thoughts are with his family at this very sad time."
Whittingham was twice Cardiff's Player of the Year and was named in the Football League Team of the Decade for 2005-2015.
Juventus star Aaron Ramsey started his career with the Welsh club and paid a touching tribute of his own to his former team-mate on Instagram.
"I will forever be grateful for you taking me under your wing," he said, accompanied by a picture of the pair playing together in their Cardiff days.
"You were one of the most technical and gifted players I've played with and that left foot of yours was like a wand.
"I'm proud to have played alongside you and will always remember the young vs old games and you just running the show.
"My thoughts and prayers go out to your family, rest in peace Whitts, was too young."
