West Midlands born Dan Martin is being reported as leaving Cannondale-Garmin at the end of this season.
Martin will ride the Vuelta a Espana for the American team but is expected to leave after turning down the offer of a new contract.
He is now a successful rider in the peloton with wins in the Liège-Bastogne-Liège and the Tour of Lombardy and a stage win in the 100th edition of the Tour De France.
Trek Factory Racing, Etixx Quick Step and possibly Team Sky are all being cited as possibly suitors.
