West Brom failed to score in their opening three games and appeared to be heading for another blank until Gareth McAuley's injury-time header snatched a 1-1 draw at Craven Cottage.
Clarke was glad to end the barren run and is confident his side has plenty of firepower after adding summer recruits such as Nicolas Anelka, Scott Sinclair, Stephane Sessegnon and Victor Anichebe.
"I think for the team it was just a goal that was deserved on the balance of play," said Clarke.
"In the second half we were on the front foot and created two or three chances in open play.
"We had to wait a long time for our first goal of the season but now it's arrived, hopefully the floodgates will open.
"Victor played last week at Craven Cottage and as you saw, he's big, strong and powerful and can hold the ball up well for us. That's something we didn't have in the team going into the season.
"Stephane is quick and lively, he's direct and likes to take people on, he's a dribbler and an entertainer and hopefully he gets many chances here to entertain the crowd.
"All the signings over the summer have intensified and boosted the squad. Training has been good over the last couple of weeks and hopefully we'll start to see results on the pitch."
The Baggies boss expected West Brom to make a stronger start to the season, but believes they will raise their standards even higher in this weekend's home clash with Sunderland.
"I'm not where I want to be," he said. "I want to be further up the league and have more points and scoring more goals. But I think we're moving in the right direction.
"I said to the players before the Fulham game that I wanted a better performance than the previous game, which was a poor one against Swansea. And last week was better.
"Slowly, slowly, the team will improve throughout the season."
