David de Gea has admitted Saturday was a 'horrible day' after Manchester United were humiliated against Brentford.
United were defeated by Brighton on the opening day of the season and a response was expected against Brentford, but Erik ten Hag's side regressed again and they were shell-shocked at the Community Stadium, losing 4-0 after a spineless performance.
After De Gea's blunder gifted Brentford the lead within 10 minutes, United were unnerved and they never recovered. De Gea made another mistake for Brentford's second goal and the London club scored another two before half-time arrived.
