Luton manager Rob Edwards, speaking to BBC Match of the Day: "They [my players] gave absolutely everything. They [United] dominated the game in those opening stages, which we kind of knew would happen.
"But I thought we grew into the half and there was a big chance for Carlton Morris. We rode our luck once or twice but when you come to Old Trafford you are going to have to do that. Most teams will. Getting in at half time at 0-0 was crucial and then I look at the second half and I am just so proud of the players.
"We showed bravery with the ball and had almost half the possession. For Luton Town to come to Old Trafford and do that shows progression. The disappointment is how we conceded - second or third phase from a free-kick. And then creating chances and speeding the game up in those moments was difficult for us in the second half.
"We had more of the ball in the second half than we did against Liverpool. We have controlled the game. It allowed them to get more men behind the ball and for us to speed it up in the right moments. A lot of our attacks against Liverpool were in transition.
"The biggest chance was in the first half, from a faster attack, with Carlton's header.
"I can see us building and progressing with my own eyes. It is one thing coming to Old Trafford and being fearless but ultimately it is about getting points. The return we have at the moment isn't enough after 10 games.
"Everyone in the world can now see that we are competing. We now have to find a way to get something when maybe we don't quite deserve it. We are a little bit flat. I am so proud of them and the supporters applaud us.
"But today it was an opportunity to get something and we haven't done. We have had three tough away games recently and we have learned. We will keep doing the things that keep us in games and build on that."
