Cape Town - Tottenham manager Mauricio Pochettino felt the first penalty awarded to Manchester City in their 4-1 win on Saturday should never have been.Erik Lamela was deemed to have fouled Frank Lampard in the penalty area on 20 minutes at the Etihad, with Sergio Aguero converting from the spot to give City a 2-0 lead.Aguero went on to net another spot-kick on his way to scoring four goals on the day, although Spurs skipper Hugo Lloris made sure he would not get a hat-trick of penalties after denying him from 12 yards out earlier in the first half.But Pochettino claims the first penalty call changed the complexion of the game and believes the decision from the referee was not the correct one, although he tried to remain upbeat after his side were single-handedly dismantled by Aguero."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," said the former Southampton boss, who also saw Roberto Soldado miss from the spot for Spurs."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."
