Gareth McAuley's dramatic injury-time header cancelled out Steve Sidwell's strike and secured a vital point for West Brom as they left Craven Cottage with a battling 1-1 draw.
Having endured a sluggish start to the campaign, Clarke admits there is more to come from his team as his close-season signings continue to adjust to their new surroundings.
On the draw, Clarke said: "I think the way we played, we deserved to get something. When you go into injury time still one down and haven't scored your first goal of the season, you get a bit anxious.
"I said to someone on the bench I fancied us to score by the end and Gareth (McAuley) does what he does best and attacks corners.
"We have good set-piece delivery and guys who can attack the ball in the air."
He added: "Victor is a big, strong striker. He showed some good qualities. He had some good chances – one particularly he is disappointed with – but I've told him the chances will keep coming.
"When you make a number of changes right on deadline day it is difficult enough but when they go away for 14 days with their countries, you have to find a way (to cope)."
Another new signing, Stephane Sessegnon from Sunderland, missed Saturday's clash with Fulham after complications over his work permit.
He said: "Stephane needs a work permit. The change from the work permit he had at Sunderland to the one he needs at West Brom, there is a little delay.
"But hopefully he will be available to face his former team Sunderland next weekend."
