The data contains 10 full games of tracking data (at 10fps), SkillCorner's dynamic events and phases of play for those 10 games, and physical aggregate data for midfielders in 175 games. I think that's about as different as it can get, but I might be biased.

About the Dutch syrup, people only put this on pancakes, but it works really really well if your marinade needs some sugar but don't want it to be sweet.

Spring onion, Lao Gan Ma crispy chili oil, peanut butter (although we use home made "sunflowerseed butter"), Dutch syrup called "schenkstroop" (small drop will have a big effect on marinades), miso paste, sambal, sesame paste. To a lesser extend Chinkiang black vinegar, gochujang and anchovis.
