The 20-year-old made a number of appearances in a wide left position for the Eagles` Development side last season but is equally adept on the right or up front and is a fantastic dribbler of the ball.
Having represented England at under-16, under-17 and under-18 level,
Allassani played a key role in the three Lions' Victory Shield triumph in 2011.
He has yet to make a senior appearance for Palace, but played with the first-team during the last pre-season.
