The Swans defender also believes that the club are now an attractive proposition for new recruits.
Garry Monk has made four additions to his ranks during the current transfer window, with goalkeeper Kristoffer Nordfelt, left-back Franck Tabanou, winger Andre Ayew and striker Eder brought to South Wales.
Ayew can, arguably, be considered the biggest coup of that bunch, with several other sides, including a number in the Premier League, having competed for his signature before he chose the Liberty Stadium as his new home.
Williams, though, believes all of the new recruits will bring important qualities to Monk's squad.
“The guys have done a good job of bringing in new players with good personalities,” he told swanseacity.net.
“On the pitch, they are learning the way we play and paying extra attention to what the gaffer has to say. They are really good guys and talented players – they will definitely add quality to the group.”
A lot of people admire Swansea
Williams is also encouraged by the fact that players now want to come and play for the Swans.
Garry Monk’s side have enjoyed a meteoric rise recent years, surging from the bottom of the Football League pyramid to now being a solid top-10 side in the Premier League.
Monk enjoyed a fine first full season in charge last year and gained plenty of plaudits for the style he has his side playing with. Williams believes it is that approach, with the club's profile building around the world, that has helped them bring in players of proven ability.
“It’s great that we can attract players of this quality,” he added.
“It seems like we are getting players that are our first-choice. People want to play at Swansea, and we are a club that is talked about around the world. A lot of people admire the way we play.”
