Manchester United and UEFA have expressed their shock at the terrorist attack in Manchester after a bomb killed 22 people. United held a minute's silence before their last training session before flying to today's Europa League final in Stockholm. UEFA however, insists there is "no specific intelligence" to suggest Europa League final may be the target of an attack.
