Chelsea manager Rafa Benitez admitted key decisions went against his side in their 2-1 FA Cup semi-final defeat to Manchester City.
The Blues were denied a penalty when trailing 2-1 for a Vincent Kompany shirt-tug on Fernando Torres, and City's Sergio Aguero was also fortunate to stay on the field after a crude two-footed stamp on David Luiz.
"You can see the pictures, it's very clear," Benitez said of the penalty incident.
And on Aguero's stamp the Spaniard said: "I will not talk about players, but the penalty decision was crucial."
"These two decisions, especially the penalty not given, made a big difference," Benitez added.
