Crystal Palace have completed the signing of Lille left-back Pape Souare.
When he was appointed as manager this summer, Hughes inherited a Potters outfit with a reputation for football that was direct, physical and often very effective.
He has indicated his intention to get the Staffordshire club playing in a more dynamic, attractive manner without entirely abandoning the aspects of the old style that had proved successful.
There was evidence of both an on-the-floor passing game and the more familiar lofted deliveries into the box in Saturday's 2-1 Barclays Premier League win over Crystal Palace at the Britannia Stadium - Hughes' maiden home game in charge, and the first points he has collected in the job.
And asked after the contest about making new signings before the window closes on September 2, Hughes said: "We need a few extra faces and possibly a little bit more pace in the side than we have at the moment.
"So we will look for that type of player I would suggest.
But a lot of clubs and managers are looking at the same types of players, so it is not easy to get them over the line at the moment."
So far this summer, Hughes has signed two defenders in Erik Pieters and Marc Muniesa, as well striking a deal that will see striker Juan Agudelo join Stoke in January.
He added: "We are trying to get a few more bodies in just to add to the quality we have got.
"This window has been quite frustrating in fairness. But we are still in the mix for a number of players.
"Hopefully we will get positive news next week, but if we have to wait until the last minute, we will do that. It has not been easy, but we just have to stick at it."
Hughes' opposite number Ian Holloway has made a host of additions to newly-promoted Palace's squad this summer and he is also looking to bring in further players.
Holloway, who has lost the services of the departed Wilfried Zaha and has the likes of Yannick Bolasie and Glenn Murray injured, said: "I need to get some more people in to help by the end of this week, because we only have a few more days now before the window slams shut in your face.
"I have a bit to do to help the boys. The ones I have added have helped, but we need a little bit more I feel."
Three summer signings came into the Palace first XI for the Stoke game - midfielder Jose Campana, winger Jason Puncheon and striker Marouane Chamakh.
Chamakh opened the scoring in the 31st minute, latching on to a long ball by outmuscling Ryan Shawcross, cutting inside to fool Robert Huth and firing past Asmir Begovic.
Charlie Adam equalised in the 58th minute with a neat finish and four minutes later, Stoke netted what proved to be the winner when Chamakh failed to clear the ball and Huth's perseverance sent it towards Shawcross, who slammed it home.
Holloway was keen to praise the contribution his summer arrivals had made, particularly first-time starter Chamakh, who he would not blame for Stoke's second goal.
"I think he is a fantastic boy," Holloway said of the former Arsenal player.
"He could have sat there, picked his money up and waited at Arsenal, blaming everybody else, but he wants to come and play for me.
"That is the first time I have picked him for the starting line-up and he has scored.
"I said to him the other week - 'if you are not picked, son, you can't score, can you', and he just laughed.
"He gave me everything.
"Hopefully he will get a new lease of life and one in one isn't too bad, is it?"
Palace, like Stoke, lost their first league match of the season last weekend, going down 1-0 at home to Tottenham.
