Originally was using Fernandes Gold card as my CAM. Was hoping to find a good English player option so I could fit Tavernier on fully chem in my squad so I tried Maddison out. He definitely met a lot of criteria I was looking for; he has fantastic pace, 4/4 star, great dribbling stats and with a hunter chem gets all of his shot stats over 90 as well. He does so well for me that I cant stop cheering Madladison on whenever he does something in game way over his price point. I'm not sure what the deal is with players who have a high curve stat, but Madd feels like he has the finesse trait without actually having it. I find myself scoring goals from outside of the box pretty consistently with his curve. The only downsides that make him not really a top card are his poor physical stats, and not quite top tier stam. The stamina part is never really an issue for me since I play him as a straight up CAM and use stay forward instruction. I find I often have to sub my other midfielders who all have 87+ stam first. The poor physicals are something you will notice with him, you can't exactly sprint past someone who is just as quick like I can with the Rooney SBC card, but if you play around this it's not too bad.
