leaving West Brom in February
Former midfielder Di Matteo, 41, spent six years at Stamford Bridge where he won two FA Cup titles, the League Cup and the Uefa Cup Winners' Cup.
"If you see the technical staff in front of me, and my appointment of Roberto, these are people who like the quality of the game," said Villas-Boas.
During the 1997 FA Cup final, Di Matteo scored what was then the quickest goal in a cup final at Wembley, a 30-yard strike after just 42 seconds, to help Chelsea on their way to a 2-0 win over Middlesbrough.
The following year, the Italian scored again in the league cup final against Boro and made it a hat-trick of goals in a final when he found the net against Aston Villa in the 2000 FA Cup clash at the old Wembley.
During the 2000-2001 season, Di Matteo sustained a triple leg fracture against Swiss side St Gallen that sidelined him for 18 months. He eventually retired from playing in February 2002 at the age of 31.
