Clarke, who replaced Dean Keates as Walsall's full-time manager following a dismal season which saw the Saddlers relegated to League Two, has already added Stuart Sinclair and James Clarke to his squad and has been linked with a host of other players as the season nears.
The Mansfield-born boss admitted that he has been on the phone constantly in a bid to get things sorted but insisted that it has been good to get his hands dirty with the season edging ever closer.
Speaking via the Express & Star, Darrell said; "It has been busy. My phone has constantly been attached to my ear speaking to people and trying to get things sorted out and organising things.
"It’s pretty much what every football manager up and down the country will be doing. Albeit I have started a little bit early and maybe some of them are on their holidays, but no it has been good to get cracking."
