Manchester United v Barcelona (Kick-off 7.45pm). The showpiece match of the European campaign takes place this evening, as the teams meet at the Stadio Olimpico in Rome. This is a repeat of last season's semi-final, which United won 1-0 on aggregate to set up a final against Chelsea in Moscow and their third European Cup triumph. Barca have lifted the trophy on two occasions, the most recent of which came in 2006 with their 2-1 victory over Arsenal in the final. Subsequent programmes subject to change.
