Tottenham boss Mauricio Pochettino felt the penalties were decisive in their 4-1 defeat at Manchester City.
City striker Sergio Aguero hit all four of their goals in the 4-1 win.
Pochettino said: "Kun Aguero had a very good day. He scored it was a very good performance from him.
"It was a great game but I'm disappointed with the result. It was tough for us but we need to take the positives and improve.
"The third penalty finished the game for us because at the time we had possibilities to score.
"But the first key moment of the game was City's first penalty - for me it wasn't a penalty.
"The next was our penalty miss and the big save from Joe Hart just after. That was a big moment."
