Coutts, which is expected to be worth about $1 billion, was put up for sale by RBS in early August.

The Italian bank found Coutts' assets the most interesting among the available options, the FT said, citing people close to the bank.

The UK-based bank recently hired Goldman Sachs Group Inc (>> Goldman Sachs Group Inc) to seek buyers for Coutts.

Julius Baer (>> Julius Baer Gruppe AG) , the Swiss private bank, expressed interest in Coutts in September.

Intesa, which is planning to expand in UK, is looking at asset managers, insurers and private banks as options, the bank's chief executive Carlo Messina told the newspaper in an interview.

Intesa, Coutts and RBS could not be immediately reached for comment.
