Bundesliga side RB Leipzig are reportedly close to signing rising star Umaro Embalo, 16, from Portuguese side Benfica.

Embalo has played for Benfica's youth teams since 2015 and is the captain of Portugal's Under-17 team.

The right winger has reportedly also been monitored by Real Madrid, Barcelona and Manchester United, but the German league club are said to be the front-runners in the bid to sign him.

The teenager has yet to play for Benfica's senior side, but has played five games in UEFA's Youth League.

German daily Bild confirmed Thursday that, after RB's director of sport Ralf Rangnick jetted to Lisbon last week, Benfica president Luis Filipe Vieira flew to Leipzig by private jet for more talks on Wednesday.

Embalo should cost around 15 million euros ($18.3m), plus extras based on future performances.

Meanwhile, according to Danish broadcaster TV3, RB Leipzig are also close to signing Mads Bidstrup, 16, from FC Copenhagen, a midfielder who Rangnick has previously expressed an interest in.
