Jens Lehmann, the former Arsenal goalkeeper, has sparked a unique controversy by claiming that Celtic and others are violating Arsenal's trademark brand by using the term 'Invincibles'. 11th February 2024; St Mirren Park, Paisley, Renfrewshire, Scotland, Scottish Cup Football, St Mirren versus Celtic; Celtic Manager Brendan Rodgers This comes after Lehmann seemingly secured the branding rights to the term, historically associated with Arsenal's unbeaten Premier League campaign in the 2003-2004 season.

Celtic's own legendary 2016/17 season, where they completed an unbeaten domestic campaign, has been celebrated as the 'Invincible Treble.' However, Lehmann's recent acquisition of the trademark rights to the 'Invincibles' tagline for PS30,000 could potentially restrict Celtic's use of the term.

According to Lehmann, his action was motivated by the upcoming 20th anniversary of Arsenal's unbeaten season, noting the increasing popularity of the 'Invincibles' name.

Lehmann told the Daily Mail, "I had the idea because the name 'Invincibles' becomes more and more popular approaching the 20th anniversary. Nobody had it, so I was looking into it. I was ready to get the branding rights for our group, so everybody who's using it is violating our brand. Sometimes you have guys from across Europe, Africa or Asia who are using it.

"They could have done that without permission and named themselves 'the Invincibles whatever'. They can't do it anymore."

It's bizarre how someone can be so pressed about a simple word used to describe a season. Celtic won three trophies without losing a game, therefore, have every right to use the word invincible when describing the season.
