There is not a lot of love in the boxing world, and that certainly applies in the case of Anthony Joshua and David Haye.
The two heavyweight fighters have regularly traded barbs in the media, with Joshua publicly backing Tony Bellew before they took to the ring for the first of their two bouts last year.
Joshua famously said in relation to that fight: "I would love it if Bellew landed a ‘haymaker’ and put a sock in David Haye’s mouth."
Meanwhile, Haye had previously stated that he would have had no trouble in defeating Joshua when at his peak.
"I'd have fought him on my first fight back from retirement (in 2016) because I know I can beat him."
At the end of the day, Haye couldn't back up his big talk and fell to defeat against Bellew on both occasions.
While the first fight saw Haye hindered by an Achilles injury, the second bout saw Bellew record a convincing TKO in the fifth round, which sent the former world champion into retirement once and for all.
You may have thought that the icy relationship may have thawed over time, but this video of Joshua making clear digs over the injury record of Haye with his own doctor shows that is far from the case.

In all truth, Joshua has much more important things to think about as he prepares to put his three title belts on the line against 39-year-old Russian Alexander Povetkin at Wembley Stadium on Saturday evening.
While a large number of his and boxing fans at large are disappointed that he is not taking on Deontay Wilder despite the repeated call-outs by the American, Joshua rates the 2004 Olympic gold medalist highly as an opponent, ranking him third behind Wladimir Klitschko and Joseph Parker.
He has alluded to the fact that a possible fight against Wilder or Tyson Fury is still on his agenda, but for now, his focus is well and truly on his Russian opponent.
