Liverpool have the option to end Juventus star Arthur's season-long loan early.
The Reds secured Arthur Melo from the Italian giants on deadline day.
The Brazilian midfielder was signed as cover, with several Reds stars in that position injured at present.
According to Tuttomercatoweb, there is a clause in the deal that allows Liverpool to send him back to Italy early.
If he does not perform, or they move for another player in January, Melo may head back to Juventus as early as January.
That means the Brazilian has until the World Cup to impress boss Jurgen Klopp at Liverpool.
