The Potters manager confirmed to RAC1 he was in attendance to check on striker Sandro Ramírez and winger Adama Traoré.
"They are two options," Hughes revealed, before insisting he was visiting to take in a game.
Meanwhile, Eusebio Sacristan, the Barca B coach, admitted there could be business done with Stoke this week.
"It's a matter of talking to all parties and evaluating the situations that may occur. We are at a time when the market is open.
"We'll have to see what the players think."
Both Sandro and Traore have tasted first team action for Barca this season.
