There are currently four Italian coaches working in England’s top flight division as well as a German, Portuguese, Spaniard, and Dutch managers.
Ferguson, who was speaking in his role as a UEFA coaching ambassador after the annual Elite Club Coaches Forum in Switzerland, claims the attractive nature of the league is responsible.
“The Premier League is such a magnet for all the top coaches,” Ferguson told reporters.
“It’s not just the Italians. There’s Jurgen Klopp who is German, Jose Mourinho who is Portuguese and Pep Guardiola who is Spanish.
“There’s a school of Italian managers establishing in the Premier League but it’s a collection of international managers now because I think the Premier League is probably the most attractive league in Europe now.
“When you see the television figures in America, for instance, it’s all English football.
“It’s such an attractive game, the English game, and that’s why these managers are there, to take the challenge.”
The UEFA coaches forum is where top football managers on the continent meet to debate trends in the game which influence their work and possible improvements they’d like to see.
The likes of Red Devils boss Jose Mourinho, Arsenal manager Arsene Wenger, Barcelona gaffer Luis Enrique, Manchester City coach Pep Guardiola, Liverpool manager Jurgen Klopp as well as PSG boss Unai Emery were among those in attendance.
