3. John Mensah (Ghana)
Position: DC Age: 30 Former Club: Rennes The former Sunderland long-term loanee might not have made particularly big waves in the North East when he was brought in temporarily by Steve Bruce to add international experience and class to the beleaguered Black Cats' backline. Mensah proved popular with the crowds, and with fellow player Michael Turner, but his injury problems ultimately meant a permanent deal failed to materialise, and the Ghanian headed back to Lyon. Via former club Rennes, he is now available once more as a free agent, and though his stats aren't as immediately intriguing as some others on this list, he is a good option. Mensah's experience is massive, and his defensive stats all come it at 14 and above with a couple of 16s and 17s. For free, those are very good stats, and he will add much needed defensive steal to lesser Premier League sides, especially those looking for squad depth.
