Barcelona are close to signing The Argentine strikers in the summer of 2020, but Martinez ended up staying at Inter and helped them win their first Seria-A title in 11 years.
The striker has repeatedly confirmed that he is happy with Inter Milan and wishes to reach an agreement on a new contract, while Barca are focused on signing free transfer agent Sergio Aguero and Memphis Depay.
According to Sport reports that talks between Martinez and Inter Milan have now become a stumbling block, with Barca monitoring the situation.
The report adds that Catalans with financial problems will not be willing to offer a $ 90m (£ 77.2m) Inter price target for Martinez, and are willing to include Emerson on the right with a view to lowering the price.
The Argentine International still has a contract with Inter Milan for another 2 years and he scored 19 goals and 11 assists in 48 appearances in all competitions last term.
