Spurs fought back to win 2-1, but the victory was not without some hiccups.
"Southampton came at us and pushed hard first half, we've only had a couple of days with the new manager to try and do some things so it's going to take some time," Bale said to Sky Sports.
"But we had a good chat at half-time about what we could improve and we did that second half and controlled the game and deserved the victory.
"[We need to] just to be patient, solve positional issues as a team. We've only had a couple of days to work on that so just minor teething issues. We'll continue to improve for the [Carabao Cup] final at the weekend."
