The Baggies currently occupy sixth place in the standings following four wins and two draws from their opening eight matches.
However, Clarke has made it clear that he doesn't want his side to grow complacent.
"I've told anyone who will listen to me that I'm really happy with the squad I've got," said the Scot.
"If I have to go into the second half of the season with that squad, then I will be delighted. Everyone is in a good place, but you know in football as soon as you rest on your laurels, it will come back and bite you.
"We don't do that. We look to keep pushing and driving ourselves forward to get as many points on the board as quickly as possible."
West Brom travel to St James' Park on Sunday to face Newcastle United in the league.
