United are at FC Basel in the Champions League tonight.
Ferguson said: "For quite a few years now, Switzerland has been producing some good young players, like Philippe Senderos (Fulham's former Arsenal defender) and they got to the final of the Under-21 Championships last year.
"A lot of clubs are now scouting in the country.
"Basel are one of the premier teams in Switzerland, obviously, and they have some good experience. They have been in Europe quite a few times so we'll respect that."
