Manchester City will be going up against Manchester United in the final round of FA Cup on Saturday at the Wembley Stadium. United are looking to complete the domestic cup double for the first time, having lifted the League Cup in February. Meanwhile, Premier League champions City can become only the second English club after United to win the top-flight title, the FA Cup and the Champions League in one season. United fans are desperate for their side to extinguish those dreams as Pep Guardiola's men look to replicate Alex Ferguson's 1999 treble heroes.
