Tottenham Hotspur boss Mauricio Pochettino was left frustrated by the manner of his side's 1-1 draw against Besiktas in the Europa League.
Spurs had looked set to register their second consecutive win in Group C of the competition but a late Vlad Chiriches mistake allowed the visitors to restore parity with only a few minutes to go.
"In football you always can make a mistake," Pochettino said on Chiriches.
"It was an unlucky action, a difficult action in this moment.
"He made one mistake after another mistake, but we need to accept it, because this is football.
"I am very disappointed. I am angry, I am frustrated and all that you want to say, but it is 1-1 in the end.
"We conceded in the last minute, which is very disappointing, and maybe frustrating. It is hard to accept this."
