Tottenham have confirmed the appointment of former Southampton scout Paul Mitchell as head of recruitment and analysis.
Mitchell was credited with unearthing Southampton's key summer signings Graziano Pelle, Dusan Tadic and Sadio Mane that have allowed new boss Ronald Koeman to push the south coast club to second in the Premier League table.
The former Wigan and MK Dons star left St Mary's earlier this month however, and has now completed his reunion with ex-Saints boss Mauricio Pochettino at White Hart Lane.
Tottenham continue to be linked with January transfer window moves for Saints duo Morgan Schneiderlin and Jay Rodriguez, and will hope Mitchell's arrival can prise both men away from St Mary's.
"We are delighted to announce that Paul Mitchell has joined the club as head of recruitment and analysis," read a Tottenham statement.
Mitchell's arrival at Tottenham will further complicate an already-politically charged structure, with director of football Franco Baldini and chairman Daniel Levy both prominent in transfer negotiations.
Koeman, meanwhile, has maintained that Saints will carry on regardless.
"He (Mitchell) was important in that (summer transfer strategy) because we had a good scouting list and had to change a lot of our team," said Koeman.
"We like to keep everybody and Mitch did a great job in the club but on the other hand, we understand his decision because it's football.
"People are always changing clubs. Southampton does not depend on one person.
"We will bring in a good person to continue our philosophy and good luck to Paul at Tottenham."
