West Ham have issued an ultimatum to Sporting Lisbon that they are not ready to pay more than £35m for their midfielder William Carvalho.

Both clubs have been involved in negotiations over a transfer fee for the Portugal international, but haven't yet managed to reach an understanding.

The Mirror claims that the Hammers have bid £30million plus £5m in add-ons for the player, and they are not prepared to increase their offer.

Meanwhile, Sporting have put a price tag of £40m on the 25-year-old.
