Clarke's side travel North to Gresty Road on Saturday afternoon before hosting Newport County at Banks's Stadium on Tuesday evening and then visiting Plymouth Argyle's Home Park stadium next weekend.
The Mansfield-born boss has spent the summer rebuilding the Saddlers squad, adding fifteen players to the team, and admitted that he will continue to assess his team over the next three games with a view to potentially adding to his squad ahead of Transfer Deadline Day.
Walsall have made a positive start in the league, earning a win and a draw from their opening two games, the but the gaffer feels he’ll know more about his team over the next few weeks and admitted the next seven days are important.
Speaking via the club's official website, Darrell said; "The proof will be in the pudding after ten-to-twelve games. We’ve got a big week coming up with two away games and a midweek game and then we’ve got a week before the window shuts.
"I’ll be assessing the next three games. I know I need another centre forward but I’ll also be assessing if I need one or two others.
"I’ve got room for manoeuvre as the squad has been built on a reasonable budget so I’ve got a bit to play with which is good news if and when we need reinforcements, maybe a couple in this window and January as well.
"It’s not going to be a quick fix, there’s going to be bumps in the road but as long as we keep learning from them bumps and get that mentality into the football club and I think we’re slowly getting there then I think we’ll kick on."
The Saddlers arrive at this weekend's match on the back of a disappointing midweek defeat to Crawley Town, the Saddlers losing by three-goals-to-two and subsequently exiting the Carabao Cup at the First Round stage.
And Clarke wants his team to build momentum and go on a run of form, but admits he is expecting a difficult task against a Crewe side who have the ability to swap and change their approach.
Darrell added; "I’m expecting another tough League Two encounter. They’re possession based but they can mix it up with Chris Porter at the top end of the pitch.
"They’ve got good players that run off him so they’ll cause us problems but I’m sure they’ve watched the videos of us and will say that Walsall can cause us problems as well.
"If you’re going to get into the top areas of this league you’ve got to get unbeaten runs together through some course of the period. I think realistically there’s 16/17 teams that can get in the top seven this year.
"It’s a very competitive league but I think we’re amongst one of those teams."
