Toulouse hooker William Servat believes the former European Champions cannot take Connacht likely when they meet at Stade Ernest-Wallon on Saturday.
The hosts lead Pool 6 by a solitary point from English side Harlequins with two rounds of action remaining.
Connacht, who they beat 36-10 at the Sportsground back in Round 2 are first up and then a trip to Gloucester in their final game awaits.
And even though they will take confidence from the victory in Galway last year, Servat is taking nothing for granted.
"They will come here and play a lot," he said.
"They have a lot of determination and they will never stop playing.
"They are Irish players and they will fight until the end.
"Obviously the first priority is to win the game but we could be in trouble if we don't get the bonus point as well.
"But we respect Connacht and we are focused on getting the win before thinking about the bonus point."
