The youngster has impressed at the Championship side, but Saints' boss Craig Burley has said he doesn't want to let the talented defender leave the club and is negotiating a new contract to keep the player on the South coast.
Burley said, "There is no change in the situation. I spoke to his parents last week and they are very happy. Gareth will certainly be here until the end of the season and hopefully a lot longer."
He added, "We are talking to him and hopefully we can extend his contract, but he is certainly going to be a Southampton player until the end of the season."
