The former Leeds striker is impressed by the capture of the 22-year-old winger.
Indeed, the 47-year-old - who spent time at a number of different clubs including the Whites during an illustrious career - took to Twitter after the signing of the Excelsior winger was confirmed.
And Deane feels Botaka represents good business for Leeds as he has the requisite skill and speed to make a difference in the Championship.
Leeds have confirmed that Botaka will wear the number 20 shirt at Elland Road and the Deadline Day signing has explained that the size of the Yorkshire club was a big factor in persuading him to leave Excelsior.
Boss Uwe Rosler now has far more options in the final third than when he first came to the club. United's creative midfielders can offer a lot, while both Chris Wood and Mirco Antenucci appear on form - with Lee Erwin yet to introduce himself to the first team.
Out wide now, meanwhile, the likes of Stuart Dallas, Botaka and more offer Leeds plenty of excitement. Will the new 22-year-old prove a success as Deane suggests?
