Two years have passed since Anthony Joshua stopped Wladimir Klitschko and signalled his arrival as a global boxing superstar.
The battle between the all-time great and the rising star signalled a changing in the guard in the heavyweight division and turned out to be the last time Klitschko was seen in the ring.
But on the second anniversary of their historic and absorbing Wembley contest, Klitschko has dropped the biggest hint yet he could be set for a comeback.
There have been plenty of reports the Ukrainian fighter is considering returning to shake up the heavyweight division - and a message to Anthony Joshua on social media has suggested that could well be the case.

Joshua is still yet to confirm an opponent for his US debut at Madison Square Garden on June 1, and despite plenty of fans putting two and two together to make five, it is hard to see Klitschko taking on Joshua in the immediate future.
Reports in Germany, however, recently suggested Klitschko was offered a £60million, three-fight mega deal by streaming giant DAZN which it seems could tempt the 42-year-old back into the ring.
