West Ham have offered a massive £28m for Marseille star Michy Batshuayi.
The Hammers are busy searching for a new striker and are determined to complete a mega-money deal for one this summer.
However, Sky Sports says the potential Batshuayi transfer has been thrown into doubt following Britain's decision to leave the EU.
The British public voted in favour of Brexit today and it has seen a dramatic fall in the value of the pound.
The fluctuation of exchange rates following the historic referendum could put several transfers in doubt.
