Leicester boss Richard Cockerill admits that his Tigers 'did just enough' to register a 33-25 victory over Treviso in Pool 2 of the Heineken Cup.
Although Leicester remain second in the table, Cockerill insists that his side must improve before they make the journey to northern Italy to contest the return fixture next weekend.
The hosts ran-in five tries at Welford Road to secure a bonus point but Cockerill was not impressed: "We were inaccurate - we went to sleep in the second half.
"It was a lot closer than we would have liked but it's job done but no more than that.
"It certainly won't lead us to be complacent next week, so maybe it has done us a favour.
"We will have to be a lot better. Treviso were good but I don't think we were under any illusions. Two years ago we nearly lost in Treviso in the first round of the pool stage.
"The players will know they are in for a tough afternoon next week. We have got to go there and try to get five points. Whether that is attainable, we will have to wait and see."
