LaLiga president Javier Tebas would like to see Cristiano Ronaldo back in Spain but conceded he was unsure if it was "feasible" for Atletico Madrid to sign the Manchester United star.
Ronaldo is reportedly seeking a move away from United less than a year after returning from Juventus, supposedly because of a lack of Champions League football after the Red Devils' sixth-place finish in the Premier League last season.
The Portugal captain, who scored 24 goals in 38 games in 2021-22, returned to United's training ground on Tuesday having missed the club's pre-season tour of Asia and Australia.
It seems suitors for his services are not as plentiful as anticipated, with Bayern Munich CEO Oliver Kahn appearing to rule out a move, while nothing has yet come of reported interest from United's Premier League rivals Chelsea.
Atletico had also been talked of as a potential destination, though club president Enrique Cerezo described it as "practically impossible".
An Atletico fan group called for the club to rule out signing Ronaldo on Wednesday, with Union Internacional de Penas Atletico de Madrid issuing a statement on the matter saying the forward represents "the antithesis" of the team's values.
Tebas would encourage any move to bring the 37-year-old back to Spain, though, telling reporters: "I would like to see Cristiano Ronaldo in LaLiga again.
"Whether it is feasible or not for Atletico Madrid, I do not know. There would have to be some player departures if they wanted to. To sign a player of that level, you must make room."
Ronaldo spent nine years at Real Madrid between 2009 and 2018 and became the club's record goalscorer, netting 451 times in 438 games for Los Blancos.
