Southampton have more young players ready to break into their first team after the exit of several big names, says ex-Saints star Calum Chambers.
The 19-year-old right-back was the fifth player to leave Southampton this summer with a £16m move to Emirates.
But Chambers, who only made his Saints debut at the start of last season, believes more youngsters will come through the ranks.
"They have a great youth system... they'll produce more players," he said.
Chambers, whose move was finalised after only 25 senior appearances, told Arsenal's official website: "It has been a bit of a whirlwind for me.
"From under-21s to first-team football is such a big step. I think it is more mentally than physically challenging.

"I have managed to keep my feet on the ground and worked hard.
"Every experience I got was such a good feeling to go out there and play against players of such quality. I just want to keep doing it more and more."
Although he played last season at right-back for Southampton, he started his career as a midfielder.
"I was a midfielder about a year and a half ago for the under-21s," he said. "I saw an opportunity in the first team at right-back and thought that for my progress it would be best to move there.
"I used everything I learned in midfield - like first touch, scanning and all that - and brought it into right-back. I learnt how to play there with the under-21s and went through each game afterwards with the coaches and worked on little bits, and it just went from there."
