The Brazilian forward had a successful loan spell at Betis last season and is eager to rejoin the team.
However, Betis and Fajardo are facing challenges in negotiating a new loan agreement with United, who are insisting on a straight sale.
During a recent press conference, Fajardo expressed caution and respect for the situation, citing the complexity of the deal.
He emphasized the need to avoid speculation during the transfer window, while acknowledging the challenges of negotiating with a top-tier club like Manchester United.
