I used Luuk De Jong in the attached squad as the LST in a 4222 in-game in Division 5 rivals. His instruction set was simply stay forward + get in behind and he was partnered up top by Marko Arnautovic's dynamic duo card which I will also be writing a review for. I am on old-gen and used De Jong with a hunter chem-style to try and give him the best chance of breaking in behind.
I do not claim to be a good player this year but this card made it very easy to score goals and keep myself in games against better squads and players. I listed all of the games he has played even though I did quit out of two games. As far as objective cards go, he is my favorite so far and is definitely worth the rather annoying objective grind of having to score twice with Dutch players in all of those separate games. If you have Cody Gakpo and/or loan Cruyff, it will make it much easier!
I would recommend starting him but having a powerful, fast striker to bring off the bench for him in the second half. He is easily the most clinical finisher I have used thus far and that perfect link to POTM Gakpo is too good to pass on in my opinion. He's a very good option for anyone who is struggling to find a good, consistent finisher.
