London Broncos coach Tony Rea has claimed that individual errors cost his side in Thursday's 30-24 defeat to Catalans Dragons in Super League.
Zeb Taia scored two late tries for the visitors as the Broncos suffered a sixth loss of the season.
"We were at our best in terms of our effort and energy but our execution let us down from start to finish," Rea told Sky Sports News.
"I think every player across the board made an error at some stage and that is very frustrating.
"You are happy to lose if you have given your best but I do not think we did tonight. We stayed strong as a team and had a fantastic attitude but that was not enough."
The defeat has left London in 11th place in the Super League table after nine games.
