Arguably the best player at the World Cup is Lionel Messi - both before the tournament began and now out of the remaining four squads of players - and arguably the best player not in Qatar at all over the past month is Erling Haaland. They're two very good footballers and world stars.
Messi is looking to win his first World Cup, Haaland is preparing to score a lot of goals for Manchester City when the Premier League returns in just under two weeks. So, when someone is compared to or admired by these players it's certainly something of note. Not that everyone has to be 'the next Messi' or 'the next Haaland.'
For Chelsea, this is great news. One of their latest transfer targets heading into 2023, Borussia Dortmund youngster Yousoufa Moukoko, has been compared to and spoken glowingly of with Messi and Haaland in mind.
