Midfielder Jack Cork says the Swansea City players are still adjusting to the departure of captain Ashley Williams.
The Wales skipper left after eight seasons with the club to join Everton for a fee approaching £12 million.
Francesco Guidolin's side kept a clean sheet in his absence as they won their Premier League opener 1-0 at Burnley.
"Ash was such a massive part of this club and was the captain," Cork told BBC Wales Sport. "We're trying to move on now."
Swansea are seeking to replace Williams, who was signed following the sale of John Stones, now the world's second most expensive defender.
