The excitement over the former Brazil under-20 international's arrival on loan from Flamengo is however being tempered by his inability to make a telling impact at Leeds.
French website But! Football Club report comments from journalist Roman Molina, expressing warning over Adryan's 2014/15 season.
He told 20 Minutes: "He was definitely not made for English football. He played ten matches and did not leave a great memory there. He was not right for play on the wings, he has no physical impact. He is a playmaker of old, that does not really tend to fall back to defend."
Adryan arrived at Leeds with a big reputation, a former teammate of Ronaldinho at Flamengo and compared to a number of Brazilian greats.
Now he is at a crossroads in his career and a move away from English football is probably sensible, based on his lack of impact at Leeds especially in the second half of the season, where he frequently failed to even make the substitute's bench.
It can only help him that expectations at Nantes will be more realistic, he just needs his coach to show more faith in him than Neil Redfearn could muster, and be prepared to work harder on the defensive side of his game to succeed.
