The 36-year-old has come under fire for Spurs’ inconsistent form which has left the club ninth in the Premier League but only three points behind fourth-placed Liverpool.
"There has never been disunity in the squad," Friedel 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.
"Our performances against Tromso and Man United showed what team spirit we do have."
Villas-Boas hit out at critics following his side’s 6-0 hammering at Manchester City on November 24 but Friedel has praised his team-mates following their reaction from the defeat.
"Criticism after a 6-0 loss is going to come. As players, all we can do is get on the training pitch the next time and work hard,” he said.
"We had a very professional performance in Tromso in difficult circumstances with the plastic pitch and freezing cold weather. I thought we came through that and the team spirit lifted very nicely.
"Then against Manchester United we were excellent. We were on the front foot and were the better of the two teams with the better chances.
"We showed a really good reaction. I don't think you'd expect a good reaction from supporters and the press after a 6-0. You just have to avoid watching television or reading the papers and just get on with the job.
"We're now looking forward to Wednesday night's game at Fulham."
