Join us for all the action as it happens from the Champions League semi-final and Derby della Madonnina between arch-rivals Milan and Inter.
It kicks off at San Siro at 20.00 UK time (19.00 GMT) and the second leg is on Tuesday May 16.
Unlike the other times these two sides met in European competition, Milan going through in both 2003 and 2005, the away goals rule no longer counts, so if they are level on aggregate after two games, it goes to extra time.
These clubs have already faced off three times this season, in Serie A Milan winning 3-2 and losing 1-0, while Inter won the Supercoppa 3-0 in January.
This will be the 220th Derby della Madonnina in all competition with 81 Inter victories, 71 for Milan and 67 draws.
