The world of football is paying its respects to legendary footballer Gary Speed.
The Wales manager died unexpectedly over the weekend at the age of 42.
Gary became the Welsh manager in December 2010 and the national side recently beat Norway 4-1 - a third win in a row for his team.
He was a great player and during his career he won 85 caps for Wales, a record for an outfield player.
Gary played for loads of clubs including Everton, Bolton and Newcastle and lots of fans and players have been paying tribute to him.
Manchester United midfielder Ryan Giggs, who played with Speed with Wales for 13 years, said he was "totally devastated" and the Prime Minister, David Cameron said his thoughts were with Gary's family.
