Diafra Sakho celebrates after scoring the first goal for West Ham
The Hammers have gone into the summer off the back of a memorable season which saw them come close to Champions League qualification.
With the club making the big move to its new 60,000 seater Olympic Stadium home this summer, the Irons have been linked with a host of top stars in the transfer market.
The Hammers will also be keen to move players who are deemed surplus to requirements out of the club to free up space in the squad and on the wage bill.

And one of those could well be Sakho after a season of indifference amidst all that was great about Bilic's East London revolution.
Sakho became an instant Hammers hero when he signed for just £3.5 million from French side Metz in the summer of 2014.
He scored eight goals in his first eight games to earn the song 'He scores when he wants' from fans on the terraces.
But it was his hard work, chasing lost causes and harrying of defenders which really endeared Sakho to the West Ham faithful.

Striker must rediscover fitness, form and hunger
Injuries have restricted the number of times he has been able to play in his first two seasons, but he still boasts a healthy goal record of 15 in 43 games.
This season, though, he has been more out than in. Injuries and a lack of form since returning from a serious knock over the winter have hampered his progress.
The Senegal man has been making headlines for all the wrong reasons this season.
He has had a brush with the law, crashed his Lamborghini and even had an alleged falling out with Bilic, as reported by the likes of the Mirror at the time.
It looked like he was finding his feet again with a goal in the thrilling 3-2 win over Manchester United as the club waved goodbye to Upton Park.

But next time out in the final game of the season up at Stoke City Sakho missed some gilt-edged chances to make it 2-0 and seal a place in the Europa League.
One chance in particular saw the former fans' favourite compared to Carlton Cole by Hammers fans when he missed from five yards out with just the 'keeper to beat.
Stoke went on to win, Southampton leapfrogged the Hammers in the final standings and in the end Bilic's sude only secured Europa League football by virtue of Manchester United's FA Cup final win over Crystal Palace.

Time to move on for both parties?
And the general feeling on the terraces now is that West Ham must move on to bigger and better things.
Many supporters would like to see the club keep Sakho as a third or fourth choice striker. But whether he would be happy with that is another thing entirely.
There would be no shortage of takers should the Hammers decide to sell.
And if they do there is always the risk that he could find fitness, form and that hunger and desire to succeed again.
