Skysports.com understands Aston Villa are set to join the bidding for Kenya midfielder Victor Wanyama.
The 19-year-old's agent recently stated that Celtic had agreed a fee with his current club, Belgian side Germinal Beerschot, ahead of a transfer.
But new Villa boss and former Rangers manager Alex McLeish is set to rival the SPL runners-up for Wanyama's signature.
Premier League new-boys Swansea are also understood to be considering entering the race for the teenager.
Wanyama has played 11 times for the Kenyan national side and has already become an established player at club level, playing 30 games and scoring two goals.
