Southampton midfielder David Brooks wants his promotion-chasing side to cut out "slight errors" after their dramatic 4-3 win at Birmingham.
Joe Aribo scored a 96th-minute winner for fourth-placed Saints to keep them five points behind second-placed Ipswich Town in the Championship.
The victory followed back-to-back home defeats by Millwall and Hull and a 3-0 loss at Liverpool in the FA Cup.
"The performance on a whole was extremely good," Brooks said.
"If we can just not concede three goals then it's perhaps one of the best performances of the season. It's the small margins but we'll have a look as a team and try to get better.
