Internazionale are the latest Italian club to express an interest in taking Chelsea's teenage full-back Wallace, who is unlikely to be granted a work permit to play in England, on loan for the season.
Chelsea signed the 19-year-old Brazilian from Fluminense in December and allowed him to remain at the club until the end of last season. He featured for his new employers on the recent three-match tour of Asia, impressing in flashes, but José Mourinho conceded that he would have to be loaned to a European club to gain first-team football and, potentially, break into the national set-up.
Chelsea hope to address the work permit issue next summer and, if he has benefited from senior football in a leading division, will argue he should be classed as a "special talent".
The right-back was not included in the 25-man squad who travelled to the United States on Tuesday for a four-game tour and will join Nathaniel Chalobah, Josh McEachran and Lucas Piazón in securing a season-long deal elsewhere for the new season.
Inter will compete with Roma and Napoli, coached by the former Chelsea manager Rafael Benítez, in pursuit of the youngster with a decision likely over the next few days.
