At the moment no we aren't a better team and that shouldn't happen when you add a world class player to your team. Sanchez should play as a wide forward in a 3-4-3 formation or 4-3-3. We should NOT use 4-2-3-1 because it doesn't suit any of our players. Both Sanchez and Martial are wide forwards who drift inside not wingers in the 4-2-3-1. There are 2 options: 1) 3-4-3 Bailly/Jones Lindelof Rojo Valencia Matic Pogba Shaw Lingard Sanchez Martial We used this formation against Watford and Arsenal away and scored 7 goals so I'm not sure why we don't use it again. It provides a better balance for our attackers and Pogba has less defensive duties. You can also put Lukaku in Sanchez's place and put Sanchez behind and drop Lingard as well but I prefer the above team because it's more fluid on the counter. 2) 4-3-3 Valencia Bailly Jones Shaw Matic McTominay Pogba Sanchez Lukaku Martial This is also a great set up and if we can strengthen our midfield in the summer it's the only formation we should use going forward. At the moment we don't have the quality from the 3rd midfielder whether that's Herrera, Fellaini, Carrick but I feel for this season McTominay is the best option. He keeps it simple, recycles the ball, can put a tackle in as well and the whole point is that Pogba can have more freedom to create in the final third. Again Sanchez has a free role on the right but he can drift inside and link the play too. Martial stays on the left where he has been really well this season. My preference for this season is 3-4-3 but if we buy 2 midfielders in the summer I would use 4-3-3 going forward.
