Former Sunderland defender Titus Bramble has reportedly been pictured training with West Ham United on Monday.
The 31-year-old, who left the Black Cats earlier this summer, has been linked with Besiktas in recent weeks.
However, images on social networking site Twitter have emerged of the centre-back training with West Ham ahead of the new Premier League season.
It is not yet clear whether the Hammers are interested in his signature.
