Ibrahimovic and Sweden finished bottom of their Group in Euro 2016, behind Belgium, Italy and the Republic of Ireland.
We're at the semi-final stage of the competition now and Wales are undoubtedly the surprise package ahead of tonight's last-four clash with Portugal.
Real Madrid ace Gareth Bale is the star of the side as far as profile goes, and he's done his bit by netting three times, but Wales' togetherness is arguably the single biggest factor in their progression thus far.
They have a unity which the Rangers man feels is missing in a team like Sweden, where the new Manchester United striker - who retired from international duty after his country's exit from the tournament - is their flagship player.
The Gers midfielder says that the 34-year-old plays for himself, while suggesting that Bale is very much a team player despite their "superstar" status.
“Honestly, I’m surprised to see the Welsh in the semi-finals. If you look at the players, they are a real team, okay, but not great players individually," he told L'Equipe, via Sports Witness.
“They have a superstar in Gareth Bale, who plays for the entire squad: usually, the superstar plays for the superstar. In Sweden, Zlatan plays for Zlatan, he is not working for his team, and Sweden were quickly eliminated.”
Barton might or might not have a point, but the Ibrahimovic at club level could hardly be accused of selfishness after racking up 95 assists in his senior career to date, according to Stats Bunker.
During his loan spell at Marseille, Barton and the Manchester United new boy - then at Paris Saint-Germain - had a brief verbal spat with one another.
