Leicester City interim head coach Andy King was keen to point out positives in his side's performance despite their exit from the FA Cup.
The Foxes were able to draw themselves level at St Mary's thanks to an Oliver Skipp overhead kick just after half-time but conceded in extra time to exit the competition.
"I'm pleased with the performance on the main and there were plenty of positives from the game," King said.
"We played four teenagers who I thought went about things reall well, they were very mature in their performance and stuck to the game plan which is how I wanted them to.
"But in key moments we have to be better, we have to be stronger with the challenge on the edge of the box with one minute to go before half time and then don't need to give the penalty away.
"We got oursleves back into the game and we just can't concede from a set play in added time but across the game I was pleased with the performance."
