Lionel Messi returns to Barcelona is of nothing, what will he be coming back to do ? . Instead of Barcelona he should just follow Ronaldo's step look for a club that can offer to pay him very well .
Barcelona needs young players to strengthen the team more, not people like Messi that is losing strength in performance as time counts.
I guess you've not been watching Lionel Messi. He may be getting old, he may not be as strong and good as he used to but he's still an asset every big club in Europe will like to have in their team. There may be a few downside on Barcelona if they sign Messi, but his performance is not one of them. Messi is still among the best players in the world right now. You saw what he did in the world cup, you also saw his performance for Argentina during the international break (if you watched). Right now Messi has over 50 goal and assist this season, and that is his bad season. How many players in Europe today have over 50 G/A this season alone?
Messi would be a very big asset to Barcelona but the problem is, they might go back to the way they used to and just keep relying on him, making it difficult to strengthen the squad because the weak links won't be noticed much. Another issue is that players like Raphinha, Dembele and Ferran won't have enough playing time to develop because Messi would be a starter ahead of them. Also, Messi's salary might make it a little difficult to recruiting big players because there might be no money to pay them and Messi.
Messi continues to be in the spotlight due to PSG failure in the Champions League, PSG fans increasingly ridicule Messi for not being able to bring PSG to win the Champions League. Now Messi's future is being speculated, his contract with PSG is valid until June 2023. At an increasingly old age, it has not reduced the interest of big clubs in Europe to use his services, he can still be relied on even though he is not able to run as fast as he used to.
It is difficult to find players who always maintain their performance at a high level. Almost every year he always looks good, he is also very active in scoring goals and providing assists. He will not make blunders in his career, offers from Arab clubs are indeed very tempting, but his status is not an outcast player from the club he has defended which is difficult to find a new club. Barcelona are still trying to sign Messi, maybe he will have a new role under Xavi. Barcelona already has top players on the front lines, Messi can be placed as a playmaker who serves the attackers in the front row.
