Kasper Schmeichel's penalty save spared Leicester defeat against Brighton and Foxes boss Brendan Rodgers hailed his "world class" goalkeeper after the goalless draw.
The Denmark international kept out Neal Maupay's 14th-minute spot-kick after Aaron Connolly was clumsily brought down by James Justin.
It was a poor penalty from the Brighton striker, with Schmeichel not needing to stretch or extend himself to keep it out as he smothered the shot down to his right.
It spared Leicester a fifth defeat in the last 10 Premier League games as Rodgers' side continue to limp towards Champions League qualification.
"It's a really good point, a hard-earned point. I'm really proud of the performance and the attitude of the players. The endeavour and work-rate to keep a clean sheet was excellent," said Potter, whose team are six points above the relegation zone.
"I'm delighted with four points (since the restart) but there is a long way to go. We still need points but that's not the focus, we just concentrate on the next game and our performances and making sure they are good enough to get points and get enough points to stay in the Premier League.
"We are in a good place after four points from two difficult games, and games that have been in a short space of time too. With a bit of luck we could have had another three points tonight but it wasn't to be.
"We've got a little bit of a breather now before preparing for Manchester United (June 30) so we'll use that time to recover but you can see in the last couple of games that we're prepared to battle to make sure we stay in this division and that's a good sign going forward."
