Fernando Amorebieta has had Hughes under pressure since his arrival.
"You work hard to get yourself in the team," he said. "There's a lot of competition for places. I'll do my best and try and keep the spot as long as I can.
"You have to embrace it [when new players come in]. We're all in it together, and the competition keeps everyone on their toes and makes sure no one gets complacent.
"Fernando has looked quality in training and in the pre-season games. We're pretty strong with Brede, myself and Phil [Senderos]."
