Arsenal boss Arsene Wenger is full of admiration for EFL Cup opponents Southampton.
Wenger knows better than most just what quality can come from years in Saints' set-up, having poached three players from the club over the last decade.
"They have certainly been the most prolific producers of top talent in England in the last 15 years," he said.
"They have not only produced talent, but top talents. We have some examples at our club with Walcott, Alex Oxlade-Chamberlain and Calum Chambers.
"But don't forget they've also produced top quality players like Gareth Bale, Adam Lallana and of course others. They do not only produce quality players, they scout very well as well because they scouted players like Sadio Mane."
