Manchester United defender Luke Shaw says defeat at Arsenal was a "reality check".

United lost 3-2 thanks to Eddie Nketiah's 90th minute winner.

Shaw later said, "In the second half we deserved that, we were a bit passive and let them control the game completely. To concede right at the end is gutting. We were fighting to the last second but we have to concentrate for the full game and one lapse in concentration could cost you a goal.

"Always coming to the Emirates, they start really fast. We had a bit more control in the game, aggressive and winning the ball high up but we backed off in the second half and they had chance after chance. They were going to have one more chance late on.

"You have to give them credit for what they have done this season, they deserve to be at the top with how they are playing. There is a long way to go and we have to focus fully on our next game, a big semi-final [against Nottingham Forest in the EFL Cup] coming up.

"The quality of these games is getting much higher. It was tough to be involved in but these are games you want to play in and test yourselves. We are all gutted in the changing room to concede so late on and it is a reality check."
