The 'Hoops' play Hearts in the semi-finals of the Scottish cup on Sunday and Morgan is hoping the effects of the defeat don't linger too long.
"Sunday is obviously something that we are all looking forward to now," Morgan said.
"We will learn from the RB Leipzig game, we will analyse it and will look forward to the weekend now. The games come thick and fast so you can't dwell on a defeat too long.
"Obviously the end result was disappointing. I think we probably had control of the game in the first 30 minutes We've done exactly as the manager had asked and took the game to them and they changed formation.
"But it was that 15-minute period at the end of the first half which obviously cost us. The goal took the sting out of us a little bit, maybe we should have seen that out a bit better until half-time.
"We created a big chance early on and if that goes in obviously it is a different game. We had a couple of chances on the night and we need to take one of them at this level. You see that you will get punished by teams."
