Sky Sports understands Norwich have made a late move to try to beat Swansea to the signing of Peterborough defender Ryan Bennett.
Our sources reported earlier on Tuesday the Swans were lining up a transfer deadline day swoop for the highly-rated stopper.
However, fellow Premier League newcomers the Canaries have moved to block the deal at the last minute and snare the youngster for themselves.
Bennett, an England Under-21 international, has emerged as one of the Championship's most promising defenders.
Posh boss Darren Ferguson recently claimed Manchester United were monitoring the 21-year-old's progress.
The defender, who arrived at London Road from Grimsby Town in 2009, has notched up 31 appearances in all competitions for Peterborough this season, scoring one goal.
