West Ham United centre-back Jose Fonte, 34, is reportedly closing in on a move to the Chinese Super League, with Dalian Yifang appearing to be the front runners.
It was only a couple of months ago that Collins quit Wales to focus on West Ham, but the 34-year-old has seemingly been unable to convince the club that he is worthy of a new deal.
The 'Ginger Pele' has only played 12 games so far this campaign, with Slaven Bilic and latterly David Moyes frequently opting for Winston Reid, Angelo Ogbonna and Declan Rice in the heart of defence.
If both Fonte and Collins leave the club, which is looking increasingly likely, Moyes must be planning a move for centre-back reinforcements behind the scenes.
West Ham were well documented admirers of Swansea City's Alfie Mawson (Sky Sports), who Carlos Carvalhal recently dubbed one of the best defenders in the Premier League. However, after a month of interest in January, a move never materialised.
Nonetheless, it will be interesting to see who emerges as West Ham's new defensive target, should Fonte secure a switch to China and Collins follow him out the door at the end of his contract, as the Hammers look to transform their back line.
