Chris Powell has admitted that it "wasn't to be" in his side's defeat against Middlesbrough.
With 18 minutes remaining Lukas Jutkiewicz headed in to give Boro a slender victory.
Speaking to BBC Sport, Powell said: "Sometimes there's games when you just have to accept it's not going to flow the way you want and it wasn't to be today.
"We didn't have that spark that I expected from our first home match of the season."
The defeat means Charlton are pointless from their first two Championship matches.
