Atletico Madrid fans are making their voices heard as they put an effort to stop the club from signing Cristiano Ronaldo this summer transfer window.

The club have been continuously being linked to the Portuguese footballer's most-awaited transfer due to the fact they can provide Ronaldo's goal of playing in the Champions League football as well as come back to the city he lived in for nine years. 

However, Diego Simeone's side would reportedly need to massively reduce their wage bill to close a deal with Ronaldo in order to comply with La Liga's financial rules. The hindrances do not stop there, as Ronaldo previously played under Atletico's arch rivals, Real Madrid, between 2009 and 2018. Los Colchoneros supporters are therefore opposing his signing in their club.

Several fans have united behind the hashtag #ContraCR7 [AgainstCR7] on Twitter to express their anger with the hope of influencing the club's decision. "If this one comes to my Atleti, I will cancel my two subscriptions.... We are not an asylum to collect scum," one supporter tweeted. "This is not just about Atletico fans, every club's fans should reject Ronaldo," another added.

The five-time Ballon d'Or winner previously confirmed his plan to leave Manchester United this summer. He is reportedly frustrated at the lack of the team's recruitment during the transfer window and is said to be desperate to play in the Champions League next season.

The 37-year-old did not join the team in Thailand for United's pre-season tour and his absence is also expected during the Red Devil's upcoming Australia tour due to family issues. Speculation over his future continues to emerge, with Chelsea, Napoli, Barcelona, Paris Saint-Germain and Atletico Madrid among the clubs linked with him recently. Jorge Mendes, Ronaldo's agent, is seeking a team that could offer Ronaldo Champions League football and the chance to lead the side's attacking line.

According to some reports, United are ready to let the Portuguese player leave, but they still want to suggest the option of extending his two-year contract by another season. The team reportedly want to see Ronaldo join another European squad on a year-long loan and return when the club have achieved Champions League status for the 2023/24 season.
