The Rs have confirmed the appointment of Redknapp but the former Tottenham coach has admitted he was tempted by the Ukraine role and had discussions about taking the job.
"[I was] very close [to coaching Ukraine]. It was really a job that excited me, I must be honest," he told Sky Sports.
"We met the people there, they were fantastic.
"The job was exciting, it was something that I'd never done in my life before, to go abroad and coach. And it was something that I really was up for.

"Yesterday [Thursday] I was sort of almost on my way to Ukraine. It was something I really fancied doing.
"When we got the phone call saying we'd like to talk to you it changed everything around. But it was an interesting job for sure."
Redknapp will watch his new side from the stands on Saturday afternoon as they take on Manchester United at Old Trafford before taking charge of their next game against Sunderland at the Stadium of Light on Tuesday.
