The Portuguese has been the subject of criticism after Spurs' stuttering start to the Premier League season, particularly in the wake of their 6-0 hammering by Manchester City, but the Germany international is adamant that reports of a falling-out are wide of the mark.
"I don't really read newspapers, I can just say how the team is and, if you go to the training ground every day, the team spirit is very high," Holtby told the press. "There is a lot of friendship between a lot of the players.
"We all stick behind the gaffer, we give our best. Of course we had a tough time in November but [on Wednesday] we got a good result at a difficult place. Now we need another three points from the Sunderland game.

"There is a lot of negativity coming from outside but we are all sticking together. Bringing this bad mood into the team won't help. We're positive and we know that the season is long.
"We're sticking together, we're not discussing things that are happening outside - that's not our job. Our job is to get points, to win games and make the fans happy.
"We have to do our talking on the pitch. We were responsible for that disaster at Manchester City but the way we responded after that has been good. We have to carry on doing that.
"This is a new team, we have bought a lot of players and you need to give them time - people like [Erik] Lamela, who don't speak the English language.
"Every game it is coming, we will get to know each other better and better. We are doing an OK job but we are getting there. I hope we can get a winning streak now."
