Sherwood could be named new West Bromwich Albion manager today.
"I thought Tim, especially in his first managerial job, conducted himself very well," Friedel said.
"He is good enough to be a manager in the Premier League, whether at Tottenham or with somebody else."
Sherwood publicly criticised his team for "lacking guts and character" after a 4-0 defeat to Chelsea at Stamford Bridge in March.
"Not every manager is going to get along with every player at the club - that is impossible - but he got along with most of the players," Friedel said.
