Chamakh says it would be wrong to hold the pair accountable for Arsenal's unexpected loss.
"We are all responsible for the defeat. That's football. You have highs and lows," he told arsenal.com.
"The way we conceded the second goal doesn't matter. If we had conceded a top-class goal the result would have been the same, we would still have lost. We lost a Final and it's hard to take.
"We have a feeling of frustration and disappointment because we feel that we could have won the game. To be honest, I was expecting it to go into extra time and maybe to penalties but not to lose in that way."
