Birmingham City are said to have made a double swoop for Bristol City defenders Aden Flint and Joe Bryan.
Flint, 28, has been subject of interest from several clubs this summer and Bristol are thought to have sanctioned his sale if the right offer is made.
According to the Birmingham Mail, Brum boss Harry Redknapp has already lodged bids for the duo as he looks to ward off rival interest from Leeds United and bolster his defensive ranks.
Redknapp has already brought in Marc Roberts from Barnsley this summer but has previously expressed his admiration for centre-back Flint, who was an ever-present for Bristol in the league last season and has scored 29 goals in 200 appearances for the side.
Bryan, meanwhile, has garnered attention after rising up through the Robins' youth system and becoming a key part of Lee Johnson's side.
