READ: Lionel Messi At PSG: What Does It Mean For French Behemoth
Their transfers boosted TV viewing figures considerably, with broadcaster Canal Plus getting a 40% increase for Neymar's first few games.
But neither Neymar nor Ibrahimovic won a Ballon d’Or — Messi has a record six of the top awards — and PSG's revenue stream from marketing and merchandising will greatly benefit.
His staggering tally of 672 goals for Barca includes an extraordinary 50-goal season in 2012; 96 league goals and a remarkable 133 overall across 2012 and 2013; eight Spanish league and six Champions League scoring titles.
Messi has four Champions League trophies with Barcelona, a record 91 goals in a calendar year for club and country, and a 2021 Copa America title with Argentina.
Atletico Madrid goalkeeper Jan Oblak was among the players praising Messi.
"For as long as I’ve been playing, Messi has been redefining football. If it wasn’t for him, La Liga would be a very different place," Oblak posted on Twitter. “He inspires everyone to raise their game."
With his intuition, vision, touch and astute passing, Messi is about more than just scoring goals.
Since 2006, no player in Europe’s top five leagues has created more scoring opportunities for others. He's been credited with 190 assists, while five-time Ballon d’Or winner Cristiano Ronaldo is tied for sixth place with 123.
Although Messi has never won the World Cup, he belongs in a tiny group of players widely considered to be the greatest of all time: namely Brazilian Pele and the late Argentina great Diego Maradona.
No player burst onto the biggest stage quite like Pele did as a 17-year-old in 1958, scoring twice in the final as Brazil won the World Cup. He won another two World Cups and scored 77 goals for his country — one more than Messi has so far for Argentina.
