Hughes, who was part of the Manchester United team that ended the club’s 26-year title drought in 1993, takes his Potters side to Anfield on Tuesday.
And he has delivered a warning to Jurgen Klopp’s Liverpool, who are trying to halt the Reds’ long wait for a title at 27 years this season.
“Every year it’s more difficult,” warned Hughes.
“Every year it keeps perpetuating it becomes more difficult.

Jurgen Klopp says January transfers are possible
“Certainly when I was at United it was talked about before the season, during the season and at the end.
“And if if you hadn’t done it then it was debated again in a negative way.
“It was always there.
“That’s maybe why, being part of that team and being able to do that, that team is remembered and revered a little bit because we were able to break that long line of difficulty of winning the league championship.”
Liverpool last won the old First Division in 1990 and Klopp is looking to deliver their first title of the Premier League era.
Hughes reckons the German has the players to make history – and he says a first title could breed a winning run like it did for Sir Alex Ferguson’s United.
“For us it was about making your mark on the game and being part of it,” said Hughes.
“That enabled a lot of us to make our mark at United because it had taken a lot of good teams who found it very difficult clearly.
“It gets harder every year.
“Liverpool will feel this is a good opportunity to get rid of that and have a period of success like they had in the 80s and early 90s.”
“They’re capable without a doubt.”
