Northampton director of rugby Jim Mallinder paid tribute to the composure of his side after they fought back to claim a 24-15 win over Glasgow in the Heineken Cup.
A shock looked on the cards at Franklin's Gardens when the visitors raced into a 15-point lead but the Saints turned things around to eventually claim a bonus-point win.
"It could have gone a different way, and what you cannot do is underestimate sides in the Heineken Cup. We didn't do that - Glasgow are a quality team," Mallinder said.
"They have a big heavy pack with a back row that gets around the field and backs that can take their chances.
"We were under a bit of pressure, but what was pleasing was the way we came back and kept our composure. In the second half, we controlled the game.
"I think we are in decent shape. When we are on top of our game we are a hard side to beat, and we need to keep at that intensity every single week."
Glasgow head coach Gregor Townsend could not even console himself with a losing bonus point despite the dominance his side showed in the opening stages.
"We are disappointed to come away with nothing. We played very well for 30 minutes, then let them back in to the game," Townsend said.
"And we were disappointed in the end to not get a losing bonus. It was very frustrating.
"The two tries at the end of the first half got them back into the game. I felt we could have been further ahead, but it looked like a momentum shift when they scored those tries."
Mallinder admitted that he feared a repeat of the start to last season's poor European campaign when Glasgow took the early initiative.
"The Scarlets came here last season and turned us over, which started our Heineken Cup season badly, and we never really recovered," he said.
"But we didn't panic today and there were positive messages out there on the pitch."
