Rovers beat a host of other clubs to the signature of Jack O'Connell in the summer of 2011-12 and in his first season with the club he certainly didn't disappoint.
A strong commanding centre-half, Jack went on to make 35 appearances for the Academy and Reserves in an outstanding first year that saw him play a key role as Rovers reach the final of both the FA Youth Cup and the Academy League.
Those impressive displays have seen him also earn international recognition having represented England's Under-18s and Under-19s.
Jack spent time on loan with League Two side Rotherham United from the end of November, making five appearances, before linking up with York City at the end of January for in a month-long deal.
