Baggies sporting and technical director Dan Ashworth revealed this week there were unlikely to be any additions to the present bunch of players during the January transfer window.
But that is not a concern for Clarke whose side are lying in sixth spot ahead of Sunday's clash with Newcastle at St James' Park after collecting 14 points from their opening eight games.
Clarke said: "I've told Dan (Ashworth) and anyone who will listen to me that I'm really happy with the squad I've got.
"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."
Clarke began his coaching career at Newcastle under Ruud Gullit and Sir Bobby Robson after ending his playing days at Chelsea and admits he has retained an affinity with the club.
He said: "I had a great time at Newcastle. It was very early in the career of my development as a coach.
"It was the first two years out of playing. I got some wonderful friends from my time up there.
"I still keep in touch with them. The supporters are fantastic, it is a great football city and I look forward to taking my team up there and giving them a game.
"The club is still driven by a fanatical support, still driven along the lines of a big club.
"They are trying to do it in a different way by giving out really good contracts if you are a manager or a coach.
"They are trying to build a bit of stability into a club that maybe has not been known for its stability over the years."
Albion won 3-2 away to the Magpies last season and Clarke is looking for his players to bounce back from last weekend's home setback against Manchester City.
He said: "We wanted to put on a good performance against a team who were champions and wanted to be positive and we did that.
"We had our chances to win the game and immediately after the game it is a massive disappointment.
"We've had plenty of time to get over it. In football, you move on to the next game and we have to forget about last week and attack the difficult game we've got on Sunday.
"But Albion won at Newcastle last season and we will look to continue that. The players who played last year will know they are capable of going up there and getting a good result for the club."
