Peterborough United manager Grant McCann said the difference in quality in front of goal proved to be the deciding factor as his side suffered a 4-1 FA Cup defeat to Chelsea at Stamford Bridge on Sunday.
The League One side trailed 3-0 by the 52nd minute of the third-round game, but, they did manage to pull one goal back through Tom Nichols before a second Pedro goal wrapped things up.
Following the game, McCann said: "The difference in the game was they were clinical, we weren't.
"I don't think we came here and disgraced ourselves. We could've come here and defended deeper and tried to frustrate them.
"But I thought we may as well come here and give it a go. I thought we did that.
"The fourth goal just knocked the stuffing out of us. It just killed the momentum for us. We were just seeing the rest of the game out."
