Ronaldo should be the brand ambassador for the club ''AGE IS JUST A NUMBER''!
A two year contract means he'll be 42 and will be playing.
42 is old but no match to Japanese footballers ... (this is my guess.)
The oldest professional football player to play in a top-tier league match is Kazuyoshi Miura. He was 54 years and 12 days old when he played for Yokohama FC against Urawa Red Diamonds in the 2021 J1 League on March 10, 2021, according to Wikipedia.
