Graham Potter feels his young Swansea City side are growing in maturity after they battled their way to a slender victory over Millwall.
The Swans had the better of the chances at the Liberty Stadium, with George Byers firing home what proved to be the winner with a rising left-footed strike.
They also had to survive periods of Millwall pressure during the second half as the visitors pressed for a leveller.
But they came through some tense moments and made sure of the three points and a clean sheet.
Potter was proud of the way his players handled the hard-fought encounter, with the 14 players used by the Swans boss against the Lions having an average age of just 24.
It has been a season of ups and downs, with a number of players in their first full season of first-team football.
But Potter sees signs of development within his squad.
"Getting that maturity is all about the process of winning, losing, making mistakes and being successful, there is no shortcut to it," said Potter.
"We have to go through what we’ve been through, the players are playing better football, whether that is being reflected in results is another thing because the Championship is so demanding.
"But the attitude they show daily gives me a sense we can carry on improving."
