Redknapp is confident of sealing a £7million deal for Rennes midfielder M'Vila in the next couple of days.
He said: "I also liked M'Vila when I was at Tottenham.
"He's 22, played against England a couple of years ago for France, and was fantastic.
"They (Rennes) turned down £28million from an English club for him a year ago. Spurs offered £15million for him in August. The deal looks okay.
"M'Vila's had a few off-the-field problems. If he behaves himself, and plays as we know he can, he'll do well."
