Over the years, Olympique Lyon will have made countless wrong decisions. Some may not have had a great effect, but others could have taken the French club to the top.
What would have happened to Cristiano Ronaldo and Lyon if their paths had crossed? It's no easy question, but the Ligue 1 team turned down the chance to sign the Portuguese forward in a swap deal.
'They proposed an exchange between Ronaldo and another player, who would be loaned to Lyon, and I would join Sporting Lisbon. This was in 2002, he was still young (17 years old). Lyon should be displeased for turning the deal down, it's a funny anecdote', Former Olympique Lyon player Tony Vairelles told 'Canal+'.
A year later, Sir Alex Ferguson pulled out all the stops to secure the transfer of Ronaldo, who enjoyed an extremely successful spell at Manchester United, and subsequently Real Madrid. Lyon, on the other hand, suffered the brunt of Ronaldo's talent as they rued what could have been but never was.
