The Premier League outfit were shocked by the League Two minnows, following a 4-3 penalty shoot-out loss to compound a poor run of form
Tottenham left-back Ben Davies says that the team has let both manager Mauricio Pochettino and their supporters down with their performance against Colchester United following their "horrible" Carabao Cup third-round defeat.
Spurs, who were beaten finalists in the Champions League last season, crashed out in one of the bigger upsets in recent English knockout football history, against a side ranked three divisions below them.
The Premier League outfit were bested 4-3 on penalties by their League Two hosts following a gruelling 0-0 draw, to leave them without a win in their last three games.
