Hertha Berlin star Matheus Cunha is emerging as a top target for Leeds United.

BILD says Leeds' interest in Cunha is 'becoming more concrete'.

The German outlet say that Marcelo Bielsa 's side wanted a deal to be completed in the January transfer window, but could now return for him in the summer.

It is claimed that Cunha is subject of 'concrete' interest from the Yorkshire club, having already enquired over his availability six months ago.

The 21-year-old is thought to be leaving Berlin, though, but his contract - that runs until 2024 - does not contain a release clause.
