Inter chief Piero Ausilo has been in regular contact with United about a deal for the Italy international. However, Suning insist they won't pay the €10-12m demanded by United to sell.
TMW says talks are likely to continue, however, with Darmian a priority target for Antonio Conte.
It's emerged the former Chelsea manager has agreed terms with Inter, with a deal to be announced next week.
Conte will keep pushing Inter to close a deal for Darmian over the coming months.
