Bersant Celina has been backed to bounce back from his penalty miss against West Brom, by Swans boss Graham Potter.
The Kosovo international had the chance to level for the Swans with the score at 1-0, after captain Mike van der Hoorn had been brought down by Craig Dawson.
But Celina could not convert, slipping and scuffing the ball against his standing leg from the spot, with Chris Brunt clearing the loose ball.
It was the fourth penalty Swansea have missed from seven attempts so far this season.
Potter acknowledged the manner of the miss is likely to ensure Celina finds himself in the spotlight, but says the Kosovo international has the ability to learn from the experience and respond.
"It is one of those moments you don't wish on anybody, fair play to anybody who wants to step up and take a penalty," said Potter, who confirmed Celina was the designated penalty taker on the night with Oli McBurnie missing.
"It's just a horrible moment he will have to get over and deal with.
"It's easy to mock of course and I am sure he will get a bit of that, but that is life.
"He had the courage to take the penalty and it is up to us to stick by him and he will grow and get better for the experience.
"It looked like his standing foot slipped from where I was, I think John Terry had a similar one a few years ago (in the 2008 Champions League final).
"It didn't look very pleasant did it? It wasn't nice to see."
