Prior to his world heavyweight showdown in Cardiff against Carlos Takam, Anthony Joshua was paid a visit by none other than Manchester United forward Zlatan Ibrahimovic.
Ibrahimovic, who is recovering from a knee injury that has kept him out of action since April, was allowed inside Joshua's pre-match camp in the lead-up to the highly-anticipated bout.
Ibrahimovic was pictured in conversation with the boxer, and Joshua has recently explained that the Swede offered him words of wisdom, in the only way the 36-year-old Zlatan possibly could.
And, the influential words of advice from the outspoken Swede, who is aiming to return to first-team action early in the New Year, clearly worked for Joshua in his triumph.
The 28-year-old Watford-native successfully defended is WBA and IBF super heavyweight titles against a battling Takam at the Principality Stadium on Saturday night.
Joshua defeated his Cameroonian opponent in front of a packed house in the Welsh capital with a controversial 10th round stoppage.
It was a stoppage that caused heated discussion on both sides of the argument.
Many felt that referee Phil Edwards had acted prematurely in stopping Takam from continuing his challenge against Joshua, despite the stand-in having had everything thrown at him by Joshua during the contest.
Come the conclusion of the fight, Joshua's record now stands at 20 fights, 20 stoppages, in an extraordinary career which has gone from strength to strength since the 2012 Olympic Games in London.
However, the fight was far from a Joshua domination event.
He exposed himself to counter-punches from the industrious Takam, who of course only had around 12 days to prepare for the fight as a replacement for Bulgarian Kubrat Pulev.
On Monday, Ibrahimovic, a man who is famed for having a high opinion of himself, posted a photo on Twitter, which showed the pair in discussion ahead of the fight.
The post on the social networking side read: "We are perfect and we are not trying @anthonyfjoshua," and it was retweeted over four thousand times.
From a legend of the football field, to a guaranteed legend of the boxing ring.
When sporting worlds collide.
