The Supporter’s Shield winners downed the Sounders 1-0 at Qwest Field on Sunday thanks to an Edson Buddle special but it was the overall showing which caused Beckham to gush.
"I thought it was a professional performance by us. We set our lineup early and we played some good football on the night. Our togetherness is what won the game and put us in a good position. We're happy with tonight and now we have to go do a job at home,” he said.
"We kind of knew it was going to be like that because we trained on it yesterday. We just had to do the job that we worked on all week because we knew they had fast players and that they'd get chances, but we also knew that if we passed the ball around well and played our game, then we'd do well."
Beckham was also full of praise for Buddle’s 38th minute strike which will go down as one of the goals of the season.
"Tonight and also next weekend, it's going to take something like that to win this game because we're two good teams with good players,” he added. “It's going to take something special to win and get through these games. Tonight, that goal ... everyone is going to say did he mean it? Of course he meant it. He turned on the ball and there was no one else near him. It was good for us."
