Skysports.com understands Charlton are set to beat Watford to the signing of Bournemouth defender Rhoys Wiggins.
The Hornets emerged as strong suitors on Wednesday having twice had bids for his services rejected last season.
It was thought Watford were close to striking a deal for the former Wales Under 21 international but Charlton look to have stolen a march on their capital rivals.
The Addicks have enjoyed a productive summer thus far in the transfer market having this week completed deals for Dale Stephens and Danny Green.
It now looks as though they are to complete a triple swoop as they close on a player who showed last term he is one of League One's best defenders.
