crisis talks with Ronaldo. The player committed himself to another season in Manchester, but was affected by injuries early on and -- despite a sizzling end to the campaign -- was unable to help United retain the UEFA Champions League title, losing to Barcelona in last month's final. Perez is seeking to rebuild a team which finished second in the Primera Liga last season, nine points behind Barcelona, and again failed to progress past the first knockout stage of Europe's premier club competition. He failed in his first bid for the presidency in 1995, but won the 2000 elections on a promise to sign Luis Figo from Barca. Perez duly brought in the Portuguese forward and followed it up with a series of budget-busting transfers, including that of Zidane and David Beckham, as he created a team dubbed the Galacticos. United have been linked with moves to sign Bayern Munich's France star Franck Ribery and Wigan's Ecuador winger Antonio Valencia as Ferguson seeks to replace Ronaldo. Check out the latest transfer rumors and gossip. Perez has also expressed an interest in bringing Ribery to Spain from Germany. Ronaldo moved to Old Trafford in August 2003 in a $20 million transfer from Sporting Lisbon just days after scoring against United in a pre-season friendly. He made his first senior outing for the national side that November and helped Manchester United win the FA Cup in May
