Manchester City are reportedly monitoring Douglas Luiz's form at Aston Villa as they consider re-signing the central midfielder in one of the upcoming transfer windows.
The Brazilian joined City from Vasco da Gama in 2017 but did not make a single first-team appearance for the Citizens, spending two seasons on loan with Girona before joining Villa permanently in 2019.
The 22-year-old has impressed during his time with Dean Smith's side and has been a constant in their starting XI in the early stages of the 2020-21 campaign.
According to Eurosport, Pep Guardiola's side are keeping their eyes on the South American as they weigh up the possibility of bringing him back to the Etihad Stadium.
City are thought to have a buy-back option on the central midfielder, although the exact figure and details surrounding the arrangement are unclear.
Luiz has provided two assists in eight outings for a revitalised Villa this season.
