Aston Villa hope to wrap up the signing of Villarreal defender Pau Torres next week.
The Spain international has agreed personal terms with the Villans.
The Daily Mail says a fee of around £33m is also close to being settled.
As such, Torres is expected in Birmingham to complete his move on Monday or Tuesday.
He will join an impressive central defensive unit which also includes Tyrone Mings, Ezri Konsa and Diego Carlos.
