Glasgow coach Gregor Townsend admitted his side have plenty to work on after their 1872 Cup victory over Edinburgh at Murrayfield.
Townsend's side led 21-3 after 55 minutes before Edinburgh fought back thanks to tries from Roddy Grant and Tim Visser, but the Warriors clung on to retain the 1872 Cup.
"The pulse rate did go up," said Townsend.
"Edinburgh certainly got the momentum in that last period, but I know we've got a very good defence. To get three tries was great and to get the win and retain the cup was excellent.
"We know we're not the finished article. We've got a lot to work on: one is playing for 80 minutes, another is our discipline, which has got to improve. It's a continual process. We know we have to kick on now."
"We were disappointed we didn't get the fourth try. There was one that was disallowed which would've been a cracking try; I'd love to work out why that was disallowed. Hoggy was walking in there on that offload after great work from DTH (van der Merwe)."
Edinburgh coach Michael Bradley was left to rue the timing of his side's late comeback after allowing Glasgow to open up a 21-3 lead.
"Ridiculously we could've won the match, if we'd scored a try in the last minute, which would've been the greatest steal of all time," said Bradley.
"We got two tries in the match, but the key point for us is we were at home with 11,500 people, we needed to put Glasgow under pressure, but we ended up releasing the pressure.
"It's an easier game than we are currently playing, how we seem to be putting ourselves under pressure. We have a lot of work to do in that area.
"There's no question the boys have the ability to play rugby and when we get it right we can be very good and when we control the position with pressure we can be excellent. But we're not anywhere near that at the moment."
