Patterson who is from Strabane, cut short his loan deal with Linfield to sign on the Candystripes and is Declan Devine’s first major signing since taking charge at Brandywell.
The 27 year old started his career with Rochdale but first came to prominence with FC United of Manchester scoring 107 goals in 126 appearances as the club was promoted three years in succession.
After spells with Bradford Park Avenue and Droylsden, Patterson returned to Northern Ireland and signed for Coleraine. He enjoyed a rich vein of form in the Irish League, scoring 30 times for the Bannsiders in the season.
He signed a pre-contract with Glentoran but was snapped up by Plymouth before he ever played for the Glens. The big striker struggled with an Plymouth side that as in freefall and returned to Linfield for a season long loan.
He has struggled with injury this season but showed that he is back to his best with a recent hat trick for the Blues in the win over Ballycare.
The big striker won several caps under Nigel Worthington and scored against Morocco in 2010. With Michael O’Neill promising to consider League of Ireland players, the Brandywell may provide the platform for the striker to force himself back into the international fold.
Following a succession of high profile exits from the Brandywell, City fans are bound to be excited by the arrival by Patterson and will hope he can replicate the goal tally of Eamon Zayed last season.
