Barcelona are eyeing Legia Warsaw left-back Michal Karbownik.
Karbownik, a left back who currently plays for Legia Warsaw, could be available for between £7million and £9million.
Last year, Barcelona and Betis each paid half of Emerson's transfer fee from Atletico Madrid. He went to Betis in order to get regular La Liga football, while Barcelona have the option of purchasing him outright from 2021.
Karbowski has impressed this season down the left flank, and can also play in a midfield role if required.
