The minnows, who are fifth in the Slovenian top flight and had never picked up a point in European competition, claimed the most famous victory in their short, nine-year history, with Spurs striker Harry Kane labelling the result “unacceptable”.
It was the first defeat of Conte’s reign and the Italian said he was “making evaluations” about his squad ahead of the January window.
“We need players with the right mentality and with the quality, players that deserve to play for Tottenham and aspire to be competitive, to fight for this shirt, to win something,” said Conte.
“For sure, we need this. I’m making my evaluations and then I’ll speak with the club but I’m ready to continue to work in this way. But it’s important that we have to know the situation is not simple. It’s not enough to do this [clicks fingers] and change the situation.”
Conte has so far stressed the need to focus on improving the players he has and again lauded their work ethic, but admitted that is “sometimes not enough” as he gave the clearest indication yet he is not satisfied with the quality of the squad he has inherited from Nuno Espirito Santo.
“Honestly, I’m working with the team for three or four weeks and I want to tell you I have found a great commitment and there is the will, the desire to improve,” he said after the Europa Conference League defeat.
“But more time has now passed and I’m making my evaluations directly, not through the TV or through other persons, but directly, and for sure, we need to improve a lot to reduce the gap with the top teams.”
They included Ryan Sessegnon, who the 52-year-old had talked up ahead of the game, but the wing-back endured a nightmare evening as he was sent off for two rash challenges inside the opening 32 minutes.
By that point, Mura already led through Tomi Horvat’s curling effort and though Kane equalised on 72 minutes, Amadej Marosa’s strike in the fourth minute of stoppage time deflected in off Davinson Sanchez to win it for the hosts with the final kick of the game.
