I play a 4-2-3-1 formation and have welbeck as a false 9. I tried complete forward but he's done far better as a false 9. I use Sanchez as a raumdeuter due to his movement pace and finishing, although sometimes I use him as a winger and that works well. My best player though has been Memphis Depay as an inside forward on left wing. He has 18 goals, 9 assists and 9 Moms in 25 games, 100% gotta buy him at arsenal, welbeck as a false 9 just seems to work in sync with Ozil at cam and the 2 wingers. I'm 2 points behind 1st after 25 games and in final of capital one cup and still in other cups
