Bartomeu hails 21-year-old France winger.
Dembele has scored 11 league goals and 18 in all competitions since moving to Camp Nou.
Ousmane Dembele is "much better" than former Barcelona star Neymar, and that is according to Josep Maria Bartomeu.
The Catalan club’s president is convinced Neymar, who left Barca for Paris Saint-Germain in a world-record €222 million transfer in 2017, isn’t as good as Dembele, who signed for the LaLiga champions after securing a €105m move from Bundesliga club Borussia Dortmund.
He also revealed there will be no Neymar return as the France prodigy is key to the Catalan side’s project.
"It's not possible for Neymar to come to Barcelona as we have another sporting project with Dembele and [Philippe] Coutinho," Bartomeu told TVE ahead of Tuesday's Champions League quarter-final second leg against Manchester United.
"We are happy with what we have, as Dembele is better than Neymar and he is a good professional player.
"He is a young guy who arrived at a huge club and that's not easy, but he has adapted and he is much better than Neymar."
On Philippe Coutinho who has been linked with a move away from Barca since his €160m move from Liverpool In January 2018, he said: "Coutinho is an excellent player and he has the coach's confidence.
"He has contract with us and he will remain at the team, unless they meet his release clause."
