Peterborough United starlet Adler Nascimento is set to sign with Crystal Palace.
Peterborough were hoping to persuade teenage forward Nascimiento to stay after offering him a new scholarship and professional deal.
But the promising Portuguese youngster, 16, is instead on the verge of finalising a move to the Selhurst Park club, says the Daily Mail.
Nascimento had been prolific for Peterborough's youth teams and featured for their under-18s aged just 15. His progress coming through the ranks earned him involvement in Darren Ferguson's first-team plans last season.
Nascimento made his senior debut on the final day of the campaign, a 4-1 win for promoted Peterborough at Doncaster.
