Villarreal will reportedly make the final decision over whether Real Madrid loanee Takefusa Kubo remains at the club.
The Japan international is currently set to spend the campaign at Estadio de la Ceramica, hoping to continue his development after a spell at Mallorca.
Despite impressing on his four starts in the Europa League, Real are unhappy that the 19-year-old has only featured for 174 minutes in La Liga.
However, Sport claims that Villarreal will be able to have the final say on whether Kubo spends the second half of the season at the Yellow Submarine.
The report claims that Real Betis have registered an interest in the prospect, who is open to switching clubs at the beginning of 2021.
Los Blancos are expected to give the green light to a move, providing that Betis can offer guarantees over his playing time.
