Cole Palmer's first-half hat-trick, including two penalties, helped Chelsea complete a 3-1 win on the day.
"My hand is feeling the effects of thumping a door with a bit of anger," Edwards said afterwards.
"We started really positively, and it was a real promising start, and then after a couple of ludicrous mistakes, against a top team with brilliant players, it’s going to be a really difficult day for us.
"At 2-0 down, with the energy and looking at the lads on the pitch, it looked a little bit like when we first came in for a period of time. It looked a bit disjointed for a period, they got their tails up, and obviously they got the third.
“Then it was about stopping the bleeding. I thought the players reacted very, very well, once we were able to get them in at half-time and organise things."
On Tolu Arokodare's goal after halftime, Edwards added: “We're trying to change things, and we're trying to progress in the hardest league in the world.
"The window’s been quite busy with outs. There are a couple of fresh lads who have come in, who I thought were excellent.
"Like all of us, we're trying to progress and move forward and get better. Great for him. Really, really good. He did some really good things today and worked hard for the team.”
