The Italian was recently appointed at White Hart Lane following a two-year spell with Roma.
"I think it will work because [Andre Villas-Boas] has worked with a director of football before," Pleat told talkSPORT.
"He understands the role of a director of football. I'm sure Franco Baldini will do a good job st Spurs."
Baldini acted as Fabio Capello's assistant with the England national team before joining Roma.
