The Lions' 47-17 demolition of New South Wales Waratahs - helped by a 30-point haul from Leigh Halfpenny - made it five successive victories on tour. They have scored 261 points and 33 tries on tour, and it is now all systems go to meet the Wallabies in Brisbane next Saturday.
It would have been almost a perfect 80 minutes had centre Jamie Roberts not suffered a late leg injury that could make him doubtful for Brisbane. "We got what we expected," Lions head coach Gatland said.
"The Waratahs talked about taking it to us physically. They tried to do that, and I thought our guys responded to that physicality. In the end, we were just too big and powerful. The big key in this game was keeping our discipline. It would have been easy enough for someone to be taken late, then lose their head and throw a punch, it to be picked up and then cited.
"I thought our discipline was absolutely fantastic. There were little shoulders and charges and guys being taken late and stuff. That's part of rugby, people try to unsettle you a little bit, and we've got to accept that.
"It is how you respond to that sort of niggle, and I thought our guys were brilliant at it. They were a credit to the Lions and wearing that jersey because there was some provocation out there.
"We felt there has been a little bit of off-the-ball stuff in the first couple of games, but we said we were not going to bitch and moan about it. We are not going to get involved in any accusations against the opposition. We want to go out there and play some hard, physical rugby."
Roberts departed the action 10 minutes from time, which meant the Lions ending with 14 men as Gatland had already used his full complement of substitutes.
"Even when we were down to 14 men, I thought we controlled the game without being under too much pressure," Gatland added. "We will get Jamie scanned tomorrow (Sunday). The medics thought it might have been a hamstring, but he said he has never pulled a hamstring before, so he is not kind of sure. It is fingers crossed it might not be that."
Waratahs head coach Michael Cheika admitted the Lions left an impression. "I thought we got stuck right in, but where we got caught out was when we turned over the ball. Their class showed," he said. "You have got to put heat on the nine and 10 at this level. That's the game. They are orchestrating the team, the direction, the plays, so you've got to keep them hopping."
