Lionel Messi has always been a problem to use in FUT, but in FIFA 19 it seems that they have finally found a way to make him incredible. Messi, for me, finds ways to score lots of important goals. The first game I played with him I came up against someone who was much better at the game then me. However, Messi made the difference I was able to score 3 of the 3 shots I took with him. His finesse shot is virtually unstoppable. His stamina is a problem along with his physical stature. If you go to overtime the mans stamina will be gone so sprinting is not an option. I have left him in for 120 minutes and allowed him to sit in the middle of the field as strictly a passer and even without any energy left he will still drop perfect passes. I use Messi in the 4-4-1-1 formation with Suarez up top, Messi at cf, and kondogbia and tolisso as supporting cms. I would only use messi at positions where minimal aggressiveness is required and where he will be able to dribble.
