The Chelsea loanee has been discussing the Saints' infrastructure.
Bertrand has spent the current campaign on loan with the Saints from Chelsea and has been impressed with the connection between all levels of the club.
From the youth setup all the way up to Southampton's first team, the full-back is delighted that the St Mary's outfit are so welcoming to their players.
And that is exactly what sets Southampton aside, according to the 25-year-old, as a weight is taken off the younger players' shoulders.
“From the inside, you see the work the young players are going through and the link they have with the rest of the club. It’s a very closeknit environment," he said.
And, asked if this was different to other clubs Bertrand has seen, the Southampton defender replied:
“Definitely. Not only is it a big gap anyway for a young player to step up from the reserves to the first team but it makes it more of a mental gap if they’re never seeing the first team players or manager - then all of a sudden they’re expected to be comfortable in those surroundings.”
The Southampton man discussed a wide range of subjects during his interview with Sport Magazine, including what tips boss Ronald Koeman has given him on his attacking playing style.
The 25-year-old has been given real freedom to go forward this term but, at the same time, has impressed defensively - with the Saints boasting one of the best defensive records in the Premier League. They host Crystal Palace in the FA Cup later today.
