England coach Stuart Lancaster has paid special attention to the breakdown and defence after they conceded four tries against the Southern Barbarians.
The SA Barbarians got off to a strong start but a second string England team soon found their feet and outscored their opposition eight tries to four.
England won the match with a convincing 26-54 scoreline but Lancaster said that they would have to tighten up more.
"We left ourselves short and, as a consequence, spaces opened up and they (Barbarians) scored four tries," Lancaster said.
"We pride ourselves on our defence and we're not happy about that. It is something we will have to rectify.
"We are delighted to get the win though, scoring eight tries in the process, but credit to the Barbarians side."
Lancaster felt his team took several positives from the midweek clash, but cited discipline as an aspect that needed attention after flanker James Haskell receiving a yellow card for repeated infringements under referee Jonathan Kaplan.
"They absolutely made us work for everything and we learned one or two lessons along the way ourselves," he said.
"There are definitely some areas to work on going into Saturday and also next Tuesday."
Lancaster made the trip to Kimberley to see whether some of the players in the extended squad would be able to step up to Test level.
Veteran scrum half Danny Care was praised by Lancaster after his solid performance.
"I think he (Care) did really well. He set up winger Christian Wade for a good try in the first half and has a good intuitive sense of where there is space on the field," Lancaster said.
"I'm very pleased with his performance. He lasted the full 80 minutes and I'm pleased that he's got this game under his belt. It's been a while since he last played."
Against the Springboks England finished the stronger team as they scored a try on full time and against the Barbarians England did the same which pleased Lancaster.
"Playing a good last quarter is something we discussed beforehand and I think we realised that goal against the Baabaas and the boys watching from the stand would have learned a lot from that effort."
