Claude Puel admitted there was a sense of disappointment that Southampton were not heading home from their trip to the Premier League champions with all three points.
Saints earned a 0-0 draw against Leicester City, but had the chances to have been the first away team in more than a year to win at King Power Stadium.
Puel was pleased with his side’s display, as they made it a sixth game unbeaten, but admitted there was a tinge of regret at the result.
"We finished this game with a little disappointment, because we have the feeling that we could have won this game,” he said.
“We have made a very good game, with good qualities. It is difficult to play against this team, with their good organisation. They are strong in defence and the long ball is very difficult to defend, but my players produced a very good game, with many opportunities, and this is very interesting for the future.
“It's positive for the confidence, but it's a shame to finish with a draw, because I have the feeling that we have to win this game.”
Puel added: "I told my players, whenever you finish a game like this with disappointment and frustration I think it's also a good feeling, because you can see the progress.
“We improve together and all the players in the squad make progress. It's very interesting, but it's important also when we play this game to take all the points.”
