The new Leeds winger saw things get in motion a week before the transfer deadline.
And the 22-year-old says he was open to a move as soon as he heard of United's interest.
The switch, completed on Deadline Day, then went ahead very quickly, the winger has explained, with contracts, medicals and more all sorted in swift fashion.
Botaka told the Leeds site: "One week before the deadline, my agent called me and talked to me about Leeds. For me, I was open to it and all of a sudden I was taking a plane to come here and I signed, had a medical and everything.
"It happened very quick and I’m happy. I think England is the best country to play football in. Everything, the stadium, the supporters, the competition is just way better. The best players are in England, I think."
Leeds fans will no doubt look to Botaka for some excitement going forward. United are yet to hit first gear in the final third after four draws and a narrow win but are certainly showing good signs.
Brian Deane was excited by Leeds' signing of the 22-year-old and his reputation would suggest he has both pace and skill to boot.
It's about where boss Uwe Rosler will fit him in, of course, with Stuart Dallas impressing down the left and Sam Byram a mainstay on the right-hand side. Botaka is sure to get his chance at some point: will he grasp it?
