I asked the AI, but it doesn’t know anything after 2021.
Here’s an answer for 2018:
One player who had a significant impact on the 2018 World Cup was Luka Modric of Croatia. Modric was an integral part of Croatia's run to the final, where they ultimately lost to France. He was named the tournament's best player and won the Golden Ball award. Modric's performances in the midfield were key to Croatia's success, as he dictated the tempo of their matches and was also a threat offensively. His leadership on and off the field was also crucial for the Croatian team, and he played a vital role in their historic run to the final.
