Video: Chelsea goal stuns Man United as Red Devils squander two-goal lead

Man United were stunned in Portugal as FC Porto came from 2-0 down to level their Europa League tie within six minutes with former Chelsea goalscorer Samu Omorodion equalizing.

The Red Devils impressed in the first 20 minutes of the game, building a 2-0 lead thanks to goals from Marcus Rashford and Rasmus Hojlund.

This eased the pressure on Erik ten Hag as it looked like the Premier League team would take the three points, but that wasn't the case.

The Premier League club collapsed within seven minutes as Porto came from behind to level the game at 2-2.

Pepe started the turnaround with a header from close range after a brilliant save from Andre Onana, before Omorodion equalized.

The striker joined the Portuguese side in the summer after his move to Chelsea fell through. The 20-year-old started the current season in top form and fans of the London club will be wondering what could have been.

The Spanish international's transfer to the Blues was all but confirmed this summer, but the deal between Atletico Madrid and the Premier League club fell through at the last minute.

This paved the way for Omorodion to join Porto and he now pursues Chelsea's rivals on the European stage.
