Rickie Lambert pulled the home side back on level terms before the hour-mark but Adebayor managed to produce a 64th-minute winner which infuriated Pochettino.
"It was very frustrating, we are very angry about the result," said Pochettino.
"We actually dressed up as Santa Claus today and gifted them so many goals and so many chances.
"We started off quite well in the first half, we got the 1-0 and we were very close to getting the 2-0 but then when we conceded the equaliser it was very hard to get back in the game, especially in the second half it was very tough.
"It was a frustrating day because at 1-0 we were in complete control. We only have ourselves to blame."
