North London outfit Tottenham suffered a 2-1 home defeat to fellow Premier League side Leicester in the fourth round of the FA Cup today.
Andros Townsend gave Spurs the lead at White Hart Lane in the 19th minute, and it appeared to be enough for the hosts until the final minutes of the tie.
Leonardo Ulloa restored parity for the Foxes seven minutes from time, and Jeffrey Schlupp scored the winner in injury time.
What was supposed to be a straightforward win for Tottenham ended in a dramatic victory for Leicester, leading Pochettino to rue his side’s failure to “kill” the game when they had the chances to.
"We are disappointed because we played well,” the Argentine told Spurs TV. "When you have the opportunity to kill the game, you have to do it.”
"We made two mistakes at the end of the game and we paid by now being out of the FA Cup," BBC Sport quotes Pochettino as saying.
"The game was always under our control. We scored in the first half and created chances to add to it. It is football.
"We can make a mistake but I am very disappointed because I think we expect to be through to the next round. So I'm not happy."
Statistically Tottenham were better than Leicester. The hosts had 60% of the possession, took 16 shots of which six were on target, and earned five corners.
Meanwhile, the visiting Leicester had 40% of the possession, took 11 shots of which five were target, and earned eight corners.
However, one must give credit to the Foxes for pressing on for the equaliser until the final minutes of the tie.
