Higuain was spotted arriving back in Italy on Thursday, after his Milan side lost the Supercoppa Italiana to Juventus the day before.
But there is no confirmation he has yet flown to the UK to complete his Blues transfer.
And a Spurs fan on Twitter has posted an excellent ‘spotted’ joke on the social website.
“Gonzalo Higuain arrives at Heathrow.” the Spurs fan wrote, with a picture of Gonzo from the Muppets in the airport terminal.

Another football fan - who claims to support Arsenal and Inter - joked the player is instead heading to the USA to dine on takeaway food with Donald Trump.
“In a dramatic turn of events, Higuain has cancelled his medical with Chelsea and caught a flight to DC and plans to link up with Wayne Rooney at DC United. Transfer incoming! The last minute change of heart is still unknown,” the twitter user joked.
And a third football fan joked that he had spotted Higuain ordering food at the airport.
