“I think it’s fair to say that a number of players signed in the summer have made steady progress,” he said.
“I am hoping they will continue to improve their performances and that goes hand in hand with developing strong relationships with their team-mates. I think that’s going to help us.
“Then we have the possibility that we bring players to join that group who have a very high level as well.”
Victory at Plymouth in midweek means Swansea will aim to extend their unbeaten run to five games – a feat they have not yet achieved under Williams – when they take on high-flying Sunderland.
“That would be nice… 10 games unbeaten would be nice,” said former Notts County boss Williams.
“I have been fortunate enough to go through some long runs without losing in my previous role. It’s a great feeling and one I would love to replicate here.”
Swansea have no fresh fitness concerns going into the Sunderland game, but are again without Joe Allen – who is expected to be missing for around three weeks – Andy Fisher, Sam Parker, Josh Ginnelly and Ollie Cooper.
