Chelsea FC took the lead in the 30th minute when Alvaro Morata headed home Victor Moses’ cross at Stamford Bridge.
However, Tottenham soon battled back into the game and Christian Eriksen levelled for the visitors with a brilliant long-range strike.
Dele Alli then proved the match winner when he netted twice in four second-half minutes to wrap up the three points for Mauricio Pochettino’s men and deal a severe blow to Chelsea FC’s hopes of finishing in the top four.
The result left Chelsea FC in fifth place in the Premier League table and eight points behind Spurs in the race for Champions League qualification, with seven games left to play this term.
“I think our first half was really good,” Conte told Sky Sports. “I think if the first half finished with 2-0 to us I think it would be more fair than the 1-1.
“Then in the second half we started well, then we conceded the second goal, we lost the confidence. It was very difficult to come back.”
He added: “It’s a pity because we all knew the chance we had to try to reduce the gap with Tottenham.
“Now the situation is very difficult to play in the Champions League for next season.”
Chelsea FC will now have to dust themselves down as they prepare for a return to Premier League action next weekend with a clash against bitter London rivals West Ham United.
The Blues, who won the Premier League title last season in style, will then take on Southampton in the FA Cup semi-finals as the look to try and end the season with a trophy.
