Lille defender Djibril Sidibe
The Hammers have had some problems at right back over the past year; Arsenal loanee Carl Jenkinson suffered a season-ending injury in January and subsequently returned to the Emirates Stadium, whilst January signing Sam Byram also suffered injury problems following his move from Leeds.
That forced manager Slaven Bilic into playing winger Michail Antonio at right back for the final weeks of the season, and whilst Byram appears to be the future of the position for West Ham, Bilic must also move for another right back this summer.
Some names have already been linked, but France Football now report that West Ham are now planning a huge offer to sign Lille full back Djibril Sidibe.
It's claimed that West Ham are planning to offer between €17m and €18m (£13.3m and £14m) for Sidibe, but so are Paris Saint-Germain, who are in the market for another right back having released Gregory van der Wiel this summer.
The report adds that West Ham are also willing to give Sidibe a salary of at least €3m (£45,000-a-week) in a bid to lure him to the Olympic Stadium, and fend off Champions League giants PSG.
Sidibe, 23, spent most of this past season playing at left back for Lille, but is naturally fight footed and has also played at right back and the right of midfield in the past year.
The Frenchman is strong, quick and attack-minded, having notched five goals and three assists from full back last season, and is even on France's stand-by list for the European Championships this summer.
The money being talked about for Sidibe is huge, but at just 23 and with a great record for Lille, he could be a great signing for West Ham - if they can fend off PSG.
