Manchester City have been involved in some significant transfer deals with Atletico Madrid in the past.
For example, having signed club legend Sergio Aguero in 2011 and Rodri in 2019 from the Spanish club, the previous summer transfer window saw City pick up a record sale fee of PS81m that saw Julian Alvarez swap Manchester for Madrid (via BBC Sport).
Now - however - Pep Guardiola's side have set their sights on adding another Atletico player to their squad.
Although, they have some big competition to do so.
The report adds that Chelsea are the most interested club, with Bayern Munich and Barcelona also in the mix.

Guardiola admitted a midfielder could be signed in January After Rodri's knee injury led to him having to spend the remainder of the season out of action, Guardiola discussed City signing a midfielder in January as a potential way for them to replace the Spaniard, saying this on the subject back in September.
He said: "We will see.
We talked today with Txiki, we will see what's going on.
We don't have to decide tomorrow, right? We have time to see the potential problems we will have and after we will see.
"Having worked his way through Atletico's youth ranks, Barrios now has 69 senior appearances for Diego Simeone's side under his belt.
Starting six of the seven La Liga matches he's appeared in this season, the 21-year-old has the third-highest combined total of tackles and interceptions in the Atletico squad.
His overall performances in those league games have earned Barrios a season rating of 6.
9/10 from WhoScored, making him the third-highest rated Atletico player.
Taking into account his young age, the fact that he's playing regularly for Atletico and has four of Europe's other big clubs looking to sign him, it's safe to say that Barrios is an exciting player.
