Did you know? United have only progressed once on the away-goals rule in European competition - against Dukla Prague in the 1983/84 European Cup-Winners' Cup.
Opposition boss: Jose Mourinho needs no introduction after forging a reputation as one of the best coaches in the game. The former Chelsea chief has enjoyed success against the Reds with the Londoners and, before that, Porto and enjoys a good relationship with Sir Alex Ferguson. Known for his tactical acumen, he will be hoping to come up with the right game-plan for Old Trafford. Despite the speculation regarding Mourinho's future, Sir Alex thinks he could stay on past the summer.
Star man: Cristiano Ronaldo heads a galaxy of world stars and will look to follow up his goal in the first leg by scoring on his old stamping ground. The Portuguese star remains hugely popular with the United fans but it is acknowleged he is the biggest threat on the night. Some pundits feel Ronaldo is close to moving onto the same level as World Player of the Year Lionel Messi in terms of his consistency.
Quote/unquote: "These are the nights you live for. There is just something in the air, something special. Everyone comes with a spring in their step. Every supporter is that little bit more vocal. Everyone is a little bit more up for it." Michael Carrick.
Sub-plots: Sir Alex goes head-to-head with Jose Mourinho again with Real under intense pressure to secure the trophy after conceding so much ground to Barcelona in La Liga. With the final at Wembley, the Reds are desperate to return to the home of English football again after losing out to Barca in 2011. Ronaldo's return will get plenty of attention but so should Ryan Giggs' 1,000th senior appearance - if it happens as Sir Alex has promised.
