days before his transfer. In 2006, Robbie Fowler was cup-tied for the victorious Liverpool team after his mid-season return to Anfield from Manchester City. In February 1993, Arsenal re-signed defender Martin Keown from Everton, nearly seven years after he had left the club. They went on to win the League Cup and FA Cup that season, but Keown was unable to play in either of the finals, having already played in both competitions for Everton. In January 1991, defender Viv Anderson was sold to Sheffield Wednesday by Manchester United, and three months later the two teams met in the League Cup final. Sheffield Wednesday won the game, but Anderson had been unable to play, for he had appeared - and scored - in a second-round tie for Manchester United six months earlier. In another instance, Ronaldo bought out his contract with Real Madrid to move to Milan; he was cup-tied to Madrid in the Champions League. Milan went on to win the tournament, but Ronaldo was not allowed to play in any of their games. Andrei Arshavin was cup-tied in the Champions League after moving to Arsenal during the January 2009 transfer window, having earlier represented Zenit St. Petersburg in the group stage of that competition. In another example concerning Liverpool, this time in the UEFA Champions League, Fernando Morientes was cup-tied for their games leading up to and including the final of the competition in 2005, which Liverpool won. This was due to Morientes playing in the group stage of the competition with Real Madrid. Enforcement In the 1999–2000 Football League Cup, West Ham United were ordered to replay a match they had won against Aston Villa, after bringing on as a substitute Emmanuel Omoyinmi, who had appeared for Gillingham in an earlier round. West Ham lost the replay. A notable example of non-enforcement was in the 1957–58 FA Cup. Stan Crowther and Ernie Taylor would normally have been cup-tied and thus ineligible to play for Manchester United. However, they were granted an exemption and allowed to play because the club had suffered the Munich air disaster earlier that season. In that air crash, eight United players died and two others were so seriously injured that they never played again, while five others had still not fully recovered from their injuries when the match was played. The Football Association therefore waived the cup-tied rule. UEFA UEFA's rules regarding their
