Speculation has been bubbling that Barcelona superstar Lionel Messi could move over to Inter Milan once his contract expires in 2021. The fact that Messi's father has reportedly purchased a house in Milan has only added fuel to that fire.

Now, another hint has been dropped.

To advertise their team's Tuesday night match with Napoli on Chinese streaming service PPTV, Inter Milan owners have projected a silhouette of Messi on Milan's Duomo cathedral, via Anthony Chapman of The Sun.

This has to be fairly concerning to Barcelona fans, particularly after Lionel Messi harshly criticized the club after its home loss to Osasuna earlier this month. The defeat resulted in Barcelona losing the La Liga title to rival Real Madrid.

Of course, landing Messi will not be the easiest feat for Inter Milan, as he would be an incredibly expensive transfer. However, it's not every day that you can swing a deal for an all-time great, so if the opportunity is there, you have to anticipate that Inter will pull out all of the stops to ink the superstar.

Not only would signing with the Italian squad be easier on Messi's wallet in terms of taxes, but it would also reignite his rivalry with Cristiano Ronaldo, who linked up with fellow Serie A club Juventus in 2018 after spending nine seasons with Real Madrid.

Lionel Messi is widely regarded as one of the best footballers in history.

The 33-year-old has collected six Ballon d'Or awards and has 10 La Liga championships and four Champions League titles to his name.
