West Ham are interested in signing Marouane Fellaini, as manager David Moyes looks to team up with the midfielder at a third different club.
The 87-capped Belgium international was allowed to leave Manchester United after five-and-a-half years in January, to join Chinese club Shandong Luneng.

Fellaini has two years left on his contract in China, however, the Chinese FA are introducing a salary cap which means the 32-year-old would have to take a 75 per cent pay cut if he stayed beyond the end of his current deal.
West Ham boss Moyes has previously coached Fellaini twice, taking him from Everton to Manchester United on Deadline Day 2013 for £27.5m.
Fellaini has made 260 Premier League appearances during spells at Everton and United, scoring 27 goals.

West Ham have also agreed a deal in principle to sign Benfica midfielder Gedson Fernandes on an 18-month loan without an option to buy.
Another possible option in midfield for the Hammers is 21-year-old Genk midfielder Sander Berge.
Berge played against Liverpool twice in the Champions League this season, and has also attracted interest from Inter Milan and Napoli.
