The Bosnia-Herzegovina international earned his eighth clean sheet of the season in Saturday's 1-0 win over Hull City, and Hughes was quick to praise his number one.
Begovic made a crucial save from David Meyler just before the Potters broke the deadlock and the importance of the 26-year-old's performance was not lost on Hughes.
"He made a great save [from Meyler]," Hughes told reporters. "Once again he has come up with an outstanding save, it actually got deflected. At the time I thought it was a clear-cut shot but it got deflected and made it a more difficult save.
"He's done that all year, and that's what we expect of him now. He's a top keeper, in my view there's very few that are better than him.
"He's consistent, good stature, good presence, on the field and off it. All the qualities I expect of a top line keeper."
Begovic recently admitted that he was flattered by rumours linking him with moves to the likes of Real Madrid and Manchester United.
