Isco has joked that Real Betis will now require crowdfunding to sign Antony permanently.
Antony has been hugely impressive for Betis since joining on loan from Manchester United in January.
The winger has scored four goals and provided four assists in 12 appearances for Betis so far.
As reported by Fabrizio Romano, Isco said: 'We will now need to do crowdfunding to bring Antony in!.'
Antony joined United from Ajax in 2022 for £85million but struggled for consistency.
After finding himself on the fringes under Ruben Amorim, the Brazilian was allowed to depart on a temporary basis.
