Former Northern Ireland and Wolves forward Derek Dougan has died, aged 69.
Derek Dougan made 43 appearances for Northern Ireland
Nicknamed the Doog, he will be remembered as one of the great characters of the game, as well as being a very effective centre-forward.
Dougan scored over 120 goals for Wolverhampton Wanderers and was in their victorious 1974 League Cup side.
He won 43 international caps and before joining Wolves played for Portsmouth, Blackburn Rovers, Aston Villa, Peterborough United and Leicester City.
Dougan was also an outspoken chairman of the Professional Footballers' Association.
His time there overlapped with former PFA deputy chief executive Brendon Batson, who recalled: "Derek was a great champion of players' rights and conditions and he was integral part of current terms players enjoy now.
"For many years, players were treated like cattle. But he was very, very outspoken in saying that players had an important role to play and they deserved to be free and masters of their own fate."
Current PFA chief executive Gordon Taylor also paid tribute to Dougan.
"He was one of the game's most colourful characters and I was very proud to have served with him and worked under him," said Taylor.
"I had eight years under him as chairman and he led the PFA, along with my predecessor Cliff Lloyd, all through negotiations in establishing a constitution and a collective bargaining agreement, which have stood the test of time."
Born in Belfast in January 1938, Dougan played for Irish League club Distillery before joining Portsmouth.
Dougan remained at Fratton Park until March 1959 when he joined Blackburn Rovers for £15,000.
Derek Dougan played in the 1974 League Cup final at Wembley
He spent two-and-a-half years at Ewood Park before signing for Aston Villa in July 1961. Two years later Dougan was off again, this time to Peterborough United.
In May 1965, he switched to another club, Leicester City, before securing his place with Wolverhampton Wanderers in 1967.
In just over eight seasons at the Molineux, Dougan made 320 first team appearances for Wolves netting over 120 goals.
He helped the club regain get back to the First Division status in 1967 and played when they beat Manchester City in the 1974 League Cup final.
Wolves chief executive Jez Moxey said: "Everyone at Molineux will be saddened by this news.
"Derek was a very talented and colourful footballer who was much loved by the supporters during the years that he wore the Wolves shirt."
Dougan made his Northern Ireland debut against Czechoslovakia during the 1958 World Cup in Sweden and his final international appearance was in 1973.
He was also one of six Northern Ireland internationals to play for a Shamrock Rovers XI against Brazil in an exhibition match in Dublin in July 1973.
The Rovers team was in essence an All-Ireland XI and the Northern Ireland governing body Irish Football Association had opposed the staging of the game.
Dougan, who had helped organise the game, never played for Northern Ireland again and he later said that he was in favour of an All-Ireland team.
The Wolves hero had a lasting friendship with George Best and in December 2005, Dougan joined other former Northern Ireland team-mates in carrying the coffin at the Manchester United legend's funeral.
