The 32-year-old American international midfielder, who joined the Potters from MLS side Houston Dynamo in summer 2012 and has made over 180 appearances for the club, fell out of favour when Lambert replaced the sacked Mark Hughes for the second half of the Premier League season.
Cameron started just four of Stoke’s 15 games under the Scot and made just one substitute appearance in the last eight as the side failed in their bid to stave off relegation back to the Championship after ten years in the top flight.
Lambert favoured Badou N’diaye in his plans and is likely to stick with him in the Championship next term if he does remain at the helm.
Therefore, with Cameron approaching his 33rd birthday in July, it seems he will look for a move to pastures new in order to secure some guaranteed game-time as he heads into the twilight of his career.
