Gloucester trailed 16-6 at the half time interval with Walder scoring all the points and, despite drawing level at 16 apiece with 20 minutes to go, Walder immediately kicked Wasps back into the lead as Morgan acknowledged.
"The first half pretty much established the trend for how the result was going to be unfortunately."
"I think discipline was the main factor which was unfortunate given that we were squeaky clean last week but there are lots of factors to blame."
"We showed some fight and we came back into the game which was credit to a lot of the boys but it's disappointing because we felt we could have won."
The result leaves Gloucester in seventh place in the Guinness Premiership table with six games to go and Morgan knows that every game is virtually a must win from here on in.
"It's tough to win away from home but, going forward, we have to look at winning every game now regardless of venue to get to that top four spot and qualificiation for next year's Heineken Cup."
"But we have some big cup games coming up which is where every team wants to be and what better way than to start against Cardiff next week? We won at the same stage last year against the Ospreys and we want to try and get to the final and win some silverware."
"In two weeks time we could be winners and we have to to look at the potential positives of that really. We've a lot of hard work ahead of us, analysing Cardiff's strengths and weaknesses and where we can target them."
