The angry Spurs boss coated his team for not trying hard enough to press their opponents and having the “wrong state of mind" in their 1-0 defeat on Sunday.
But Davies defended himself and his team-mates, insisting they tried as hard as they could and were just as disappointed as their boss that they lost the game.
The Wales defender said: "Look it's a tough one. I think everybody worked hard. Me personally, I gave it my all.
“I wouldn't doubt that everybody else in the team gave it their all. But the performance wasn't up to scratch.
“It's hard to put it down to a lack of effort. I'm sure we will evaluate where we went wrong moving forward."
Well ahead of a packed schedule which next involves Spurs flying to Bulgaria for Thursday's Europa League clash with Lokomotiv Plovdiv.
Tottenham then face a trip to Southampton on Sunday as they go into a run of games that has already left Mourinho moaning about a fixture pile-up.
But Davies insists they just have to use each game as a chance to make up for their disappointment against Everton.
He said: “Yeah it's obviously not how we wanted to start the season. It's disappointing. But we have to look at the bigger picture. Lot more games to come."
