Rankin is described as a quick and tricky forward who scores his goals in clusters.
He failed to make the grade at Highbury but was signed for £1.3million by Bradford in 1998. His time at Valley Parade was unsuccessful and he was moved onto Oakwell two-and-a-half years later for £350,000.
His time with the Tykes has stopped and stuttered although this season he's found he has been a regular with 24 first team apperances, netting six goals in the process.
The 25-year-old is likely to partner fellow loan striker Lee Thorpe in attack on Saturday against Brighton.
