Having joined in the midst of our promotion-winning season in 1997/98, Colombian forward Ricard would go on to become our record Premier League goalscorer with 31 top flight goals.
After taking a few months to find his feet in the country following his £2m move from Deportivo Cali, Ricard rediscovered his confidence in an 18-goal first full season as we returned to England's top tier.
His speed, strength and unpredictable turn made him a tricky proposition for opposing defenders, as was demonstrated with a brilliant brace against Spurs at White Hart Lane and a goal against Manchester United at Old Trafford - our first win there since 1930.
A Colombian international, Ricard fell out of favour following the arrival of Steve McClaren as manager.
Leaving Boro in 2002 was the start of a nomadic career that took Ricard from Eastern Europe to the Far East, as well as back to South America - the forward rarely staying with one of his dozen-odd subsequent clubs for more than a single season.
