DUBAI — Dubai has launched a competition to design a 60,000-seater stadium that will be built in the emirate to stage matches at soccer's 2019 Asian Cup, three sources familiar with the matter told Reuters. The Asian Football Confederation (AFC) in March awarded hosting rights for the 24-nation tournament to the United Arab Emirates, rejecting a rival proposal from Iran. Matches are expected to be played in the UAE capital Abu Dhabi, Dubai and oasis town Al Ain. Each will likely use two stadiums, with AFC regulations stating the hosts must employ at least six for the tournament. Some design bids have already been submitted. — Reuters
