West Ham manager Slaven Bilic
West Ham's Aaron Cresswell in action with Swansea City's Leroy Fer
Cresswell has been a key player for West Ham ever since his move from Ipswich Town in 2014, and he will be hard to replace for manager Bilic - especially considering that backup left back Stephen Hendrie has been sent out on loan to Blackburn Rovers.
West Ham must now search for another left back in the transfer market, and the Daily Mail report that manager Bilic is considering his options, with a veteran left back likely to be targeted.
Leeds United's Charlie Taylor
The report claims that West Ham have had an interest in signing Walsall's Rico Henry or Leeds United star Charlie Taylor, who has become one of the Championship's left backs over the last 18 months.
Taylor, 22, looks destined to play in the Premier League, and it's claimed that West Ham were interested in moving for him just as they did for his former Leeds team-mate Sam Byram in January - but instead, Bilic wants to land a more experienced left back.

It's claimed that Bilic will pursue is likely to pursue a veteran left back on loan to plug the gap until Cresswell returns at the end of 2016, tiding the Hammers over until then whilst also bringing in experienced cover for the remainder of the campaign - though no names are stated regarding his targets.
Napoli's Ivan Strinic would be a sensible option having worked with Bilic on the international stage with Croatia, and given that he's second choice behind Faouzi Ghoulam with Napoli, a season-long loan deal could work well for all parties.
