Sir Alex Ferguson has paid tribute to his great friend and former assistant Walter Smith, who has died at the age of 73.
The Rangers legend, who won 21 trophies over two stints at Ibrox and became the second most decorated manager in the clubs history, passed away on Tuesday after a long illness.
As well as managing Scotland, Smith worked for six months as an assistant to Ferguson at Manchester United in the second half of the 2003-04 season.
The pair also worked together for Scotland at the 1986 World Cup.
