The 46-year-old swooped to add Tyler Roberts, Dan Agyei and Zeli Ismail to his ranks ahead of the August 31 deadline.
Both Roberts and Agyei netted on their Saddlers debuts with goals against Bradford and Plymouth respectively.
And Whitney is excited by the wealth of talent he is now able to call on.
“There’s goals all over the pitch now,” the manager said. “And they can all play in different areas. It was important Simeon got some minutes on Saturday.
“Ama has done really well. Zeli can come in and play in that pocket or he can play up top. Tyler can play out wide.
“We’ve got Flo Cuvelier still waiting – no one mentions Flo. He is an incredible player and is waiting for his chance now.
“But that’s what we need. It’s a long season and we have got a lot of games coming up in September now. They will all be used.”
After netting in the win over Plymouth on Saturday, Agyei revealed he was close to joining another club before Whitney made a late move on deadline day.
And the boss said he was determined to lure the 20-year-old to the Banks’s Stadium once he found out he was available.
“I made a couple of phone calls as soon as I knew he was available,” Whitney continued.
“I knew he was lined up to go elsewhere but I managed to talk him into it.
“He’s got really good energy. he’s an intelligent kid, he speaks well and he asked a lot of questions of me which was nice.
“He did really well for Wimbledon at under-21 level, he had interest from Chelsea and West Ham but decided to go to Burnley.
“And I like the Burnley players because I like how Sean Dyche does it.
“They work hard, it’s not just about in possession, it’s about out of possession as well.
“They are the players I targeted. Players who are willing to scrap when it’s not that pretty.”
