The Arsenal captain has played against this person nine times before and has failed to score in each of those games - so it was an easy choice.
Odegaard has played top-flight football in Norway, Spain, England and the Netherlands as well as in the Champions League.
He has also already won 61 caps for his country since making his debut for Norway aged 15 in 2014.
However, it is a Premier League star who Odegaard feels is the toughest he has had to come up against.
Speaking to TNT Sports, he revealed: "I think Virgil (van Dijk) is a really tough one."

Odegaard first came up against Virgil van Dijk twice in qualifying for the 2022 World Cup before his move to Arsenal.
He has since faced the Liverpool defender seven times for the Gunners.
It took the 25-year-old until his six clash with the Dutchman to get the upper hand but he has since been unbeaten in four meetings.
Despite that, though, Odegaard is yet to score when facing Van Dijk.
