The Eagles boss is happy with the performances of the 18-year-old winger in pre-season
England-born of Ghanaian descent Jesurun Rak-Sakyi has earned praise from Crystal Palace manager Patrick Vieira after impressing in a pre-season friendly fixture.
Largely a member of Palace's academy side, the 18-year-old was on target in what ended in a 2-2 draw with Charlton Athletic on Wednesday.
He was deployed on the right-wing in the starting XI, alongside academy colleague Malachi Boateng, another England-born player of Ghanaian descent.
