We took a look at how fans reacted to the news on social media.
Generally most fans appeared to be keen on seeing Van Persie wear a West Ham shirt last season.
Van Persie’s injury problems were brought up but to be fair he went through most of last season without spending much time on the sidelines and found the back of the net 22 times.
Not everybody was too impressed. Van Persie is not going to come on the cheap and is not getting any younger.
The 32-year-old did however, have an impressive debut season at Fenerbahce despite not getting on with head coach Vitor Pereira.
Even some Arsenal fans appeared worried that their former star man could be joining a rival.
West Ham have also been linked with Mario Gomez who is a few years younger and in great form. There was some debate over who is the better striker.
