Clarke, who has signed fourteen players over the summer, added winger Rory Holden, defensive utility Gary Liddle, and defender Zak Jules to his squad yesterday (Friday) and thinks he needs one more player before his squad is complete.
But with Josh Gordon, Elijah Adebayo, Mitch Candlin, and Morgan Ferrier currently the only strikers in the first-team, 41-year-old Clarke admits he needs another frontman to give his side a better chance of adapting to any challenges that may come it's way.
Speaking via the Express & Star, Darrell said; "It’s just one more center-forward I need now. That will give me a healthy squad that is flexible within formations and has a good mix of experience and ages."
The gaffer, who has added the likes of James Clarke, Mat Sadler, Stuart Sinclair, and Danny Guthrie earlier in the window, believes the arrival of the vastly-experienced Gar Liddle means he now has enough experience to be successful in League Two.
Clarke continued; "Lids is very experienced and is my fifth and final experienced player that I wanted to bring into the club.
"He can play multiple positions: right side of a centre-half three; central of a centre-half three; and as a sitting, deep-lying midfielder.
"He’s a great passer of the ball and a model pro. We’re really pleased to add him to Guthrie, Sinclair, Sadler and James Clarke – my five leaders in the group."
Darrell then went on to talk about Bristol City winger Rory Holden, who has joined the club on loan following a successful trial spell. Clarke said; "Rory is a left-footed wide player and that’s his best position in a 4-3-3, coming inside onto his left foot.
"We’ve worked with him now for a couple of weeks and had a good look at him. His attitude has been spot on. He gives me different options."
And finally, on the addition of Macclesfield Town defender Zak Jules, Clarke said; "He did very well at the back end of last season and is a young player we want to develop.
"He’s a left-sided centre-half, pacey, quick, mobile. I’m really pleased to bring him in and I think we’ve got the balance now."
