Batshuayi is a Belgian international, and would hope to replicate the success of Romelu Lukaku and Christian Benteke.
West Ham have made Batshuayi their priority for a summer transfer deal, but Spurs have a long standing interest in the striker, and were said last week by the Telegraph to have stepped up their interest.
Playing Champions League football with Tottenham is a big reason for Batshuayi to move to White Hart Lane, but there is a very simple reason he should switch to West Ham instead, and that is the chance to be the club's main striker.
At Tottenham, Harry Kane is the number one choice forward, and this is unlikely to change with the arrival of the 22-year-old Belgian.
While he will get his share of playing time with cup competitions, when push comes to shove for a big game, will Mauricio Pochettino alter his formation to accommodate both, or leave Batshuayi on the bench? The formula of one up front has worked so far for Tottenham, and it is a jump to suddenly expect a change in approach next season.
At West Ham, Batshuayi will get the playing time and status he should want. He would become West Ham's most expensive ever signing, and the face of their ambitious new era.
At a time where the club are moving to the Olympic Stadium, being the main man up front is a real opportunity to develop as a superstar, and Batshuayi has greater potential than Sakho, Valencia or Carroll in attack.
Even more intriguingly, Batshuayi could link up with former Marseille teammate Dimitri Payet who recently extended his contract with the Hammers until 2021.
This would not be Batshuayi turning down Champions League football for mid-table also rans. West Ham are in seventh place at present and committing £30 million for his signature would be a statement of intent to kick on further. Seeing Leicester City's achievements this season should inspire belief among clubs like the Hammers that they can challenge at the top.
Tottenham may seem like the more tempting option, but Batshuayi might just find happiness with West Ham too - and become their own answer to Harry Kane rather than his support act.
