Though of Ghanaian descent, Samuel Adjei was born and raised in Sweden. The speedy winger spent a couple of years at Newcastle but saw little action due to injury. When the Tynesiders announced that Adjei would be released at the end of the 2011/12 season, he joined Pools on trial and did enough in two reserve games for Neale Cooper to sign him on loan at the beginning of March. He was unfortunately injured on his Pools first team debut and returned to Newcastle.
