Portuguese replaces his compatriot, who joined Roma after leaving Spurs late last season
The Portuguese replaces ジョゼ・モウリーニョ who was sacked way back on 19 4月, bringing an end to a chaotic recruitment process.
He has penned a two-year deal at the north London club.
The 47-year-old said: “When you have a squad with quality and talent, we want to make the fans proud and enjoy.
“It’s an enormous pleasure and honour [to be here], there’s joy and I’m happy and looking forward to starting work.
“We don’t have any days to lose and we must start working immediately as pre-season starts in a few days.”
