Historically, Manchester United have been pretty damn successful in the transfer market.
Snapping up Eric Cantona from bitter rivals Leeds United was a master stroker, and spotting a gangly Cristiano Ronaldo at Sporting Lisbon turned out to be money well spent.
But sometimes – only sometimes – Sir Alex Ferguson got things wrong.
The summer United swooped for Ronaldo, who would become one of the greatest footballers of all time, they signed an absolute clanger.
Kleberson had won the World Cup with Brazil in 2002, and joined United for £6.5million from Atletico Paranaense in 2003.
Both Ronaldo and Kleberson were unveiled together at Old Trafford, posing for pictures next to a proud-looking Ferguson.
Unlike his signing buddy, Kleberson catastrophically failed to get to grips with life in the Premier League.
He looked lightweight in Manchester United’s midfield, and made pretty much zero impact at the club during his two-season stay.
It has been suggested that Kleberson was signed to help transfer target Ronaldinho decide on a move to Old Trafford.
Whether or not that is true is completely redundant, because Ronaldinho chose to join Barcelona instead.
A meagre 30 appearances later, Kleberson was shipped out by Ferguson for just £2.5m to Besiktas.
Now 37, he’s still playing today at Fort Lauderdale Strikers, who are co-owned by Brazilian legend Ronaldo.
