The French stopper has established himself among the world's finest goalkeepers since joining Tottenham from Lyon in 2012.
The 29-year-old is currently on international duty with les Bleus for Euro 2016, with Didier Deschamps's side hosting Switzerland in their final Group A clash tonight.
France have conceded once in their two games so far - a penalty against Romania - and Gallas says that the whole defence feels a lot more secure when Lloris is behind them.
“Hugo has such a strong mentality, and that is so important for goalkeepers. When he arrived at Tottenham, a lot of people were unsure," he told Spurs' website.
"The Premier League is a different way for goalkeepers - free-kicks, corners, you have to be so strong but he’s a crazy goalkeeper! We all feel secure when he’s behind us.”
Lloris did his bit for the Lilywhites last term as Mauricio Pochettino's side challenged for the Premier League title, but the North Londoners fell away in the final couple of games and ended up finishing behind local rivals Arsenal in third.
Still, Spurs will be hoping they can go a few places better next season, though with Jose Mourinho and Pep Guardiola taking charge of Manchester United and Manchester City, it will arguably be the toughest Premier League season to date.
