Swans defender Martin Olsson admitted defeat by Leicester was tough to take but vowed to “put things right” over the long season ahead.
Shinji Okazaki and an own goal from the unlucky Federico Fernandez put the Foxes in control before Alfie Mawson pulled one back to set up a tense finish.
But it was only a string of excellent saves from Lukasz Fabianski that had kept the Swans in the game, especially early on.
“It was frustrating,’’ declared Olsson. “We just didn’t come up to the standards we know we can reach.
“It’s tough to take, but we’ve got to move on. It was tough today, but tomorrow we’ve got to forget about it, learn from our mistakes and try to put it right in the next game.
“We wanted to build on last week’s win over Huddersfield, but it didn’t work out. We just didn’t click today for whatever reason.
“We did move it better in the second half but we’ve got to start the game like that and help each other.
“We must be better in possession and with our movement. We were too open and need to be more consistent with our shape, like we’ve already done this season with our four clean sheets.
“We’ve got to make the Liberty a hard place for teams to come. We have been picking up points away, but our home form needs to be a lot stronger.
“Hopefully we can put a bit of a run together at home and turn things around because there are a lot of games left.
“We must remain positive and look to come back strong. With the fans behind us, like they were in the second half today, things can only get better.”
