The Portuguese coach, 34, replaced
Villas-Boas has been taking pre-season training this week and was due to hold his first media conference on Thursday (AEST).
Friedel, 41, feels signs are positive the former Porto boss can be a success second time around in the Barclays Premier League.
"You can only take people on what you see, and from what I have seen he is a very ambitious manager, he is very organised and training has been very sharp," Friedel said on TalkSPORT.
"He has let us know he wants to come here to win things, so in the first couple of days, everything looks very good."
The American continued: "The club did a very good job of going out to get someone very ambitious.
"There are also a lot of great staff members behind the scenes here who stayed on, so there is still that Tottenham base.
"This is all positive and our fans should be excited for the upcoming season."
Friedel joined Spurs after his contract at Aston Villa expired last summer and quickly established himself as first choice under Redknapp.
