Leicester director of rugby Richard Cockerill insisted his side had plenty to work on despite seeing them start the season with back-to-back bonus-point wins in the Aviva Premiership.
Cockerill's players overcame Worcester Warriors 34-26 at Welford Road on Saturday, a week after beating London Welsh away from home, but he was far from happy with the performance even though Tigers scored five tries to Worcester's two.
"It's a perfect start if you look at the table," Cockerill said, "But it was far from perfect performance-wise. But we will take the points."
He added: "We did some really good things and we are creating a huge amount of opportunities but we also turned the ball over too much. We just played ourselves into trouble. It's easily fixed but our mindset needs to be better than that.
"Every time we recycled the ball properly there were opportunities for us. But we were sloppy at times and put ourselves under pressure and that cost us points. We need to be better than that."
Warriors head coach Richard Hill stressed he is pleased with the progress Worcester are making.
He said: "It was a huge effort on our part and I can see something building nicely.
"We are bitterly disappointed with the loss. The players are already talking about next weekend because the signs are there and things are better than last season.
"We had the worst possible start being 14-3 down after 12 minutes. We had the ball but they scored two great tries.
"You wouldn't expect to lose tries from that distance and it put us on the back foot. We lost Chris Pennell and Shaun Perry to the sin bin but we showed great character in the way we battled back."
