I have enjoyed watching every World Cup in football for the last 30 years or so.
After the 1986 World Cup and Maradona, I thought no one would be able to top it, but then other great football stars came along like Ronaldo and Ronaldinho and later Messi and Ronaldo. It is the natural course of life, some leave, others come. I am sure that at the next World Cup we will see new football stars and enjoy great football again

Mbappe will surely be a big star at the next few world cups, and I'm sure that Neymar has not yet said his last word in the Brazilian national team.
But if you are a true football fan then you will really miss Messi and Cristiano Ronaldo. The next World Cup will bring new stars but the living football wizards like Messi and Cristiano Ronaldo will be nowhere to be found. And you can never equate Neymar and Mbappe with Messi and Cristiano Ronaldo
there is so much comparision about the Messi and Ronaldo
I think they are both superstar in their own life - they have influced the life of people and have struggled alot to acheieve this sucess
Yes it is true that we are going to miss Messi and Ronaldo for there great achievement and we hope to see new players that is going to dominate that position soon. The world cup is one of the bigger football competition in the world and seeing that we are going to miss these two players is a big absence in the history of football so far. There are players that are coming up and is going to replace them when the time comes. They have really occupied many of the big position and therefore there tenure is elapsing for a similar good athletes that can replace them.
As far as I know, only Cristiano Ronaldo who have expressed that Euro 2024 might be his last dance but now that he's with Al Nassr, we're not sure what will be his plans in the future as Al Nassr expressed that they might extend Ronaldo's contract if he still wanted to play but I think it's already unlikely since he will be over 40 years old by the time his present contract ends. But for Messi, latest speculation is that he will be with the team in the upcoming World Cup because they are the defending champion and that will be likely his last dance.
But I am still not sure whether Cristiano Ronaldo and Lionel Messi will play the next World Cup or not? However I personally see no chance of Cristiano Ronaldo playing, but Lionel Messi as the reigning World Cup champion captain may have some chance of playing if he is able to perform exceptionally well at the clubs. In fact, for me, the World Cup would not be complete without living legends like Cristiano Ronaldo and Lionel Messi.
Why do you think Ronaldo has no chance to play in the next World Cup? The new Portuguese coach invited Ronaldo to the national team again, after the World Cup in Qatar, which means that he is still seriously counting on him.
Ronaldo is no longer as effective a striker as he was a few years ago, but he is still physically fit, can still score goals and wants to play for Portugal. While that is the case, it will be difficult for any Portuguese coach to leave him out of the Portugal national team. Ronaldo is an institution in Portugal.
As for Messi, I think I read his statement somewhere that he still wants to play for the Argentinian national team, so it is not impossible that we will see both Ronaldo and Messi again at the next World Cup.
