A last-gasp try from Hosea Saumaki earned Leicester a one-point win over Connacht in the Heineken Champions Cup.
Connacht led at one stage by 28 points to 10, but the visitors finished strongly to clinch a narrow 29-28 victory.
Andy Friend says it was a disappointing result.
The result leaves Connacht fourth in Pool B - with one match left to play against Stade Francais next weekend.
The top eight will progress to the last 16.
