Kop heroes Phil Neal and John Barnes plus Everton's Gary Stevens joined the city’s leaders in taking the World Cup bid inspectors on a tour of the cultural, sporting and tourism facilities in Liverpool.
"I know how much hard work the FA are putting into this bid, and with Liverpool's fantastic footballing tradition it's an amazing opportunity to be part of England's 2018 team," said Barnes to the Reds’ official website.
"The infrastructure is here, the stadia and training facilities will be here and the fans are here. I remember Mexico 1986 vividly and the passion of the people was amazing. I am 100 per cent certain that fans on Merseyside will bring colour and vibrancy to 2018 if the bid is successful.
"Everyone talks about fans bringing colour to World Cups, whether it be Jamaican fans or Brazilians, but our fans would bring their own unmistakable flavour to a World Cup on Merseyside."
Neal expressed his delight in being involved as an ambassador for the 2018 World Cup bid.
"This bid means a great deal to a passionate footballing city like Liverpool," he added.
"Speaking as a player, I always appreciated the chance to play in major tournaments, but speaking today as a fan, it would be great to be involved again. I am delighted to be an ambassador for 2018 and I will do all I can to help.
"To be part of the 2018 World Cup would be fantastic and it would offer a great platform to build on all the good work done in the Capital of Culture year. If we did win the bid to become a host city, Liverpool would create a magnificent festival atmosphere."
