Arsenal midfielder Gilberto Silva echoed the disappointment of his team-mates after Wednesday's UEFA Champions League defeat to Barcelona.
The Gunners succumbed to a 2-1 defeat at Stade de France in Paris, despite taking a half-time lead with ten men through a Sol Campbell header.
The turning point in the match came midway through the first half when Gunners goalkeeper Jens Lehmann was sent off for a professional foul on Barca striker Samuel Eto'o.
The Brazil World Cup player believes Arsenal may have had better fortune, had Lehmann stayed on the pitch.
"The referee had two options - send him off or let the game flow by allowing the goal and we stay with 11 men," Gilberto said.
"Maybe we would have had a better chance then to change the game.
"But when we play a team like Barcelona with 10 men, they've got good quality and it's very hard.
"I think the team performed so well, we scored first but they knocked us out, so we are very disappointed."
Team-mate Cesc Fabregas was also despondent following Wednesday's defeat to his former club.
"It's difficult to play 10 against 11 since the beginning of the game against a team like Barcelona, but we've shown character and we've tried our best," he said.
