Into the Dragons' den: United must battle history as well as a daunting Porto side
History is against Manchester United in their quest to reach the Champions League semi-finals.
No British side has ever emerged victorious from a European clash at Porto.
As the Red Devils prepare for the latest installment of their Quintuple quest, they know they will have to take on not only the raucous home crowd at the Estadio do Dragao, but also decades of history.
With the quarter-final tie even at 2-2 after the first leg, the Red Devils will almost certainly need a win against Manuel Jesualdo Ferreira's side to progress.
But in more than 20 attempts spanning almost 40 years, British teams are still waiting for a victory against Porto on Portuguese soil.
