Marcelo Loffreda insists anything can still happen in Pool 6 of the Heineken Cup after his side lost in France.
Leicester were outmuscled for their second successive time following their defeat in Dublin to Leinster on the opening weekend.
But Tigers head coach Loffreda believes pool leaders Toulouse's five point advantage can be resurrected with only two matches remaining.
Loffreda said: "This pool is not finished for us. We have still got two games left to play and anything can happen.
"Toulouse were better than us and especially in the finer details of the match. We should have scored two tries in the second half but you can't afford to make mistakes like that.
"We have to be more clinical and we're disappointed not to get the bonus point.
"Leicester are a strong team but we need to build our confidence and belief for our last two games."
