Richard Wigglesworth admitted there wasn't just one area of the game to pinpoint as the reason for defeat away from home against Newcastle Falcons.
A second-half comeback fell short at Kingston Park, seeing Tigers suffer a second successive league defeat.
Speaking post-match, the Leicester Tigers Head Coach said: "It wasn't just one thing, there were a number of things that weren't good enough today."
"We put ourselves in some poor positions today and they took advantage of that, which is a credit to them, and we pride ourselves on being a disciplined team and weren't that today.
"I thought Newcastle were very good today too, I don't want to take away from them. They deserved the victory.
Discussing the comeback, which included securing a four-try bonus-point with the final play of the game, the Tigers boss admitted it was pleasing to take something but didn't change the level of disappointment in the away changing room.
"We showed some real fight in that second-half to come away with a point," he said.
"After the first-half, we didn't deserve to take anything away from today but I am proud of the way they lads rallied to earn it and fix some things up out there we discussed at half-time.
"While pleasing to get a point, there is no question that it isn't what we came here to get and we are disappointed to have lost. That's the overwhelming emotion; disappointment."
Harry Simmons was helped from the field with a leg injury in the second-half but, while it may add to the "dozen" unavailable to Wigglesworth, there was no room for excuses.
"It is a challenging place to come and play anytime but while missing a dozen, it's going to be a bigger challenge, however it's not an excuse," said Wigglesworth.
"I'm not expecting much change in terms of availability next week, so we'll just keep working hard and whoever is available to represent Leicester Tigers will be expected to deliver a performance better than we did for today's 80 minutes."
