Fonte has only been at West Ham for a year after signing from Southampton for a fee believe to be around €10million.
However, this season injury problems have restricted him to only eight appearances, and the door could be open for him to leave.
West Ham co-owner David Sullivan publicly ridiculed Fonte when he was signed by Slavan Bilic, so it comes as little surprise that the 'Hammers' are willing to let the Portuguese leave.
"My kids begged me not to sign them," he said, referring to Fonte and Robert Snodgrass.
Dalian Yifang could have a busy few days as they are also rumoured to be interested in Yannick Carrasco.
