shocker Antonio Conte's response as Tottenham are dumped out of the FA Cup by Middlesbrough

Tottenham manager Antonio Conte insisted he would not hit the panic button after a woeful performance from his side saw them dumped out of the FA Cup at Championship side Middlesbrough.

Teenager Josh Coburn was the hero as Middlesbrough produced another upset by knocking out Tottenham with a 1-0 extra-time victory in the fifth round.

Boro dumped Manchester United out on penalties at Old Trafford in the fourth round and followed it up in style to beat Spurs, with 19-year-old Josh Coburn’s 107th-minute strike settling the tie.

The Championship outfit were the better side throughout, booking their quarter-final spot and ensuring Spurs will end another season without a trophy after an abject display on Teesside.

Who knows how Antonio Conte will react to this defeat as their inconsistency continues to derail any progress and this result could have implications over his long-term future as well as that of Harry Kane, whose desire to win silverware is consistently not met at Spurs.

Only a strong finish in the Premier League and a late surge into the top four can rescue this season, but that looks a stretch on this evidence.

Conte hinted he was ready to leave Spurs after their 1-0 defeat at Burnley last Wednesday, but he offered a more balance response to this latest setback.

"For sure the result is not good and we have to be frustrated," said the Italian. "It was a pity because in these type of game you have to start and kill your opponent. If you give them hope, they will take confidence and improve during the game. Then anything can happen.

"First of all, it is important to say that Middlesbrough played a good game, deserves respect and congratulate them for the win. We have to reflect on our performance and on the game we played.

"These type of games, in these trophies away from home, you have to try to kill the game quickly. Your opponent has to understand that the night will be difficult, instead we can do much better and in the end Middlesbrough deserved to go to the next round.

"This is part of our process. I repeat, we have to try to avoid the up and down up and down and there is only one way to improve the situation is to work and learn about the defeat. We have to go ahead and we will try to do our best this season.

"We have to give our best for the rest of the season, then we will see what is our position and the evaluation of our season. It is early to say something about this."

Tottenham's last win in the FA Cup came back in 1991, two years before their star striker Harry Kane was born.
