Up for the cup: Real Madrid boss Jose Mourinho
Real Madrid boss Jose Mourinho branded it 'the match the world is waiting for' and more than 200 million TV viewers are expected to tune in to watch the Spanish giants take on Manchester United on Wednesday night.
The Champions League last-16 tie at the Bernabeu will be covered live by 40 television channels and 16 radio stations.
Real's Champions League showdown with United will be covered by 500 communications media representatives from all corners of the globe.
Four hundred print journalists and 105 photographers, the maximum capacity that the stadium can accommodate, with a total of 220 communications media from most of Europe, Africa, the US, the UAE, Japan, China, Mexico, Argentina, Brazil, India and Israel.
Kevin Alavy, managing director of Sport+Entertainment, an agency specialising in sport sponsorship, is expecting a global audience of about 200million.
'It may well be that this is the most watched last-16 match in the history of the Champions League,' he told the Daily Telegraph.
It is also poised to attract the most bets. William Hill were expecting £20million to be wagered in the UK alone, only £5m less than the 2011 final between United and Barcelona at Wembley.

P.S. But if watching two of the biggest sides in the world doesn't do it for you, tune into Liverpool's Youth Cup match at Histon instead...
