Villas-Boas's position at the club came under question last week following the team's 6-0 thrashing by Manchester City in the Premier League.
However, Friedel believes that the Portuguese coach is the right man to lead the Spurs forward this season.
"The squad is together and the whole team and all the players back the manager. He's a very good manager," the American told Sky Sports News.
"Yes, everyone was upset after the 6-0 loss, we were upset at losing out on the three points and embarrassed at the scoreline, but we stuck together."
Spurs are back in Premier League action on Wednesday night when they travel to London rivals Fulham.
