Tottenham Hotspur have failed to qualify for the knockout stages of the Champions League.
Pochettino bemoaned the lack of quality that Tottenham showed in the competition, after they lost 2-1 to Monaco in France on Tuesday.
Spurs were thoroughly outplayed by Monaco in that fixture, with their only victory in Europe this season coming against CSKA Moscow.
Pochettino suggested that changes would be made if Spurs were to qualify for the Champions League again this season.
And Pochettino insisted that none of Tottenham’s squad disagreed with his analysis of their exit.
The Argentine boss said: "Like always I was very honest. I think we struggled to be competitive in two tough competitions like the Premier League and Champions League.
“We struggled a lot and we showed that we don't show enough quality to compete and to be in the top. We are unbeaten in the Premier League after 12 games and after five games in the Champions League we lose three games, and it's obvious we don't show enough quality to share them and be competitive in both competitions. I think it's very obvious and we all [the players and staff] agree about that."
Tottenham will now have to avoid defeat in their final group match against CSKA Moscow to ensure that they qualify for the Europa League.
Spurs are next in action at the weekend, when they take on Chelsea at Stamford Bridge.
