Tottenham Hotspur are leading the race to sign Maxi Gomez.
Spurs view the Celta Vigo striker as the ideal back-up for Harry Kane, according to The Mirror.
West Ham United came close to signing the Uruguayan in January and remain interested in acquiring his signature.
The Hammers are waiting to see if Arnautovic leaves for China before pursuing a deal.
Gomez has a release clause of £43m in his Celta contract.
