Ruben Amorim insists Manchester United’s Europa League semi-final is not done, despite the Reds taking a three-goal lead into next Thursday’s second leg at Old Trafford.
Casemiro’s header and a double from Bruno Fernandes put United in the driving seat at San Mames and Athletic Club could not respond.
The Basques played the final 55 minutes with 10 men after Dani Vivian was sent off for hauling down Rasmus Hojlund in the box.
Fernandes converted the penalty for United’s second goal, and it was a moment Amorim saw as a turning point.
But, in his post-match interviews with the media, the head coach added that a similar thing could always happen to the Reds in M16, and that we should not take anything for granted.
