Carlton Cole has attempted to prove his doubters wrong following a failed medical test at West Ham United.
The 29-year-old was poised to return to the club just months after being released at the end of the season.
However, an offer of a short-term deal fell through when he failed to prove his fitness during a medical earlier this week.
After receiving a number of jibes, Cole took to social networking website Twitter to post a topless photo of himself showing off his physique.
The club is still working with Cole on his fitness.
