A tweet captioned ‘The greatest?’ from the official Champions League account has caused plenty of rival fans to weigh in with their opinion

The official Champions League account wished Lionel Messi a happy birthday on Saturday as he turned 30, but were probably not expecting a backlash on Twitter. Their caption asking if he is “the greatest” caused Cristiano Ronaldo fans to get involved, with them being quick to salute the Real Madrid attacker.

Some Barcelona and Messi fans said that there was no need for a question mark in the tweet, but these were outnumbered by irate Ronaldo fans who feel that the Portuguese is better than his great rival.

“You spelled Ronaldo wrong” was a common theme, with many fans posting Ronaldo gifs and pictures to show their support for the Portugal international

Messi has also been receiving numerous birthday messages from fellow players, teams and fans on social media.
