The Argentine scored his first league goal for the Seagulls since joining on loan from Leicester in last night's loss to Manchester City.
Hughton said: "It has been difficult for him because Glenn has played the majority of games and you get into a rhythm.
"I thought he looked a little rusty at the start of the game but he improved as the game went on with a bit of confidence.
"I thought overall his performance deserved it (the goal)."
Asked whether the deal could become more permanent, Hughton replied: "We have him on loan at this moment. He is still a Leicester player and he will come into our thoughts but we have a lot of decisions to make in the summer."
