Williams wary of 'very capable' Luton
Two of the three teams who were relegated from the Premier League last season now occupy the Championship's automatic promotion slots.
But while Sheffield United and Burnley are contenders to make an immediate return to the top flight, the third side who came down in May, Luton Town, are only three points clear of the second tier's relegation zone.
The Hatters have had a difficult time since their one-season stint in the Premier League came to an end, with Rob Edwards' team sitting 19th in the Championship.
They host Swansea City on Saturday afternoon having lost three of their last four games, and conceded 12 goals along the way.
Luton have been unable to find any consistency this season, while their tally of 33 league goals against means they have the second worst defence in the division.
Yet as Swansea head to Kenilworth Road, Luke Williams is convinced Luton's form will improve at some point soon.
"I don't know for sure because you need to be inside the camp, but I imagine the pressure and everything that comes with Premier League football can take a lot out of you," said the Swansea boss.
"To come down and have to go again can be difficult.
"But what I would say is that I don't think they are going to be there for long. They are a very capable group of players and at some point they are going to find some form. I just hope it's not this weekend."
Swansea go to Berkshire with some confidence having won two of their last three away games.
Yet Luton's home form is decent, with Edwards' men suffering only one loss on their patch since August.
