The former Manchester City and Celtic forward arrived at the Midlands club last summer, signing on a free transfer when his Celtic contact expired, although he did not enjoy a positive season.
He made just eight appearances for the Baggies, before leaving the Hawthorns in January to sign with Al-Hilal on loan until the end of the campaign.
He signed a two year contract when arriving at the club last summer, but with no plans to be utilised by Tony Pulis this coming season, he cancelled his deal for the benefit of his career.
The 30-year-old totalled almost 250 appearances for the Bhoys prior to his move to West Brom, but his influence has never reached it’s same height.
Pulis is keen to bring a more youthful look to his team, and Samaras does not fit into his view for West Brom, as they plan to move forward in the coming season.
There are no indications as to whether Samaras has a new club lined up, although his agent hinted that a return to Celtic could be on the cards this summer, as reported by Talking Baws.
