Speaking to Viaplay, Glasgow skipper Kyle Steyn admitted the squad are "buzzing" to have Adam Hastings back at Scotstoun after his time with Gloucester.
"We all love Hasto, he still has tons of mates here and he's played this brand of rugby before," Steyn told Viaplay. "We're buzzing to have him home."
Steyn also admitted his side were caught "off guard" by a Cardiff side Warriors that went in 13-0 half-time deficit to move second in the URC and before the interval ahead at the interval.
"Credit to a great Cardiff side, they put us under a lot of pressure," he added. "We're saying all the right things, we knew what was coming but they still caught us off guard.
"You can say all you want but you have to start doing it.
"We're buzzing for Duncy [Munn], even though he only got 40 seconds. He's a Warrior now and always will be. We have Max [Williamson], big Al [Samuel], Fez [Euan Ferrie] at six. It's a great test for the young boys, and it's a good sign for us as going forward."
