BRUSSELS, March 25 (Reuters) - German private equity fund Aurelius is interested in buying the Belgian unit of French retailer Carrefour CARR.PA, Brussels-based L'Echo newspaper reported on Wednesday, citing unidentified sources.
Other potential buyers are lining up, L'Echo said, but not many, it added, citing unidentified sources.
Carrefour's annual revenues were close to 4 billion euros ($4.64 billion) over the past few years, the newspaper said.
Carrefour, which has recently announced the sale of its Italian and Romanian units, last month said it would focus on its three main markets France, Spain and Brazil.
Carrefour and Aurelius did not immediately respond to requests for comment.
