Hugo Lloris has credited Mauricio Pochettino with saving his Tottenham career, admitting he was "asking himself questions" before the Argentine's move to north London.
Spurs have begun 2016 in fourth place after taking maximum points from their three Christmas fixtures -- the only team other than Stoke City to do so.
Another victory against Everton at Goodison Park on Sunday would enhance Tottenham's title credentials, but their form is a far cry from Lloris' second season at White Hart Lane, when coach Andre Villas-Boas was replaced by Tim Sherwood in December 2013.
Although Sherwood led Spurs to a top-six finish before being replaced by Pochettino, his reign was disharmonious and Lloris admits it was tough.
However, the France captain says he has been transformed since the Argentine's arrival.
"I've flourished completely here," Lloris, who signed a new five-year contract shortly after Pochettino joined Spurs in summer 2014, told L'Equipe.
"I can even say that since the arrival of Pochettino I found new benchmarks.
"My second season here was complicated, I had kept a certain level of performance but collectively there were too many gaps and it had been against the big teams.
"I had not felt a strong club, but rather an unstable one, with a coaching change in the middle of the season, just the opposite of what I like to see in football. I was actually asking myself questions until Pochettino arrived."
The keeper, however, had his confidence restored in the club as soon as the former Southampton boss arrived at White Hart Lane.
"Even when it was not working yet, he said: 'Do not worry, we will get there.' His speech was clear, we suddenly knew where we were going," Lloris said.
"With the quality of the workforce, and work ethic that is in training, there is no reason that we [won't] progress."
