Upgrading full backs, adding new ball playing defender and adding new CM in 3 midfield will increase the number of goals and will make us play better, more control we take of games more we will score. Our defence depth need to be upgraded in some way, our defence let us down often, more than our attacking. Bailly is first choice, Jones/Smalling perhaps but 3/4 choice. Blind? No, Darmain? No, they all need to be replaced immediately. If Jones getting an injury again, he will need to be replaced, not worth.
Jose can get us to score more than 100+ goals like he did with Real Madrid in 11/12, he upgraded fullbacks in Real Madrid, all of sudden, Real Madrid smashing a lot of teams - 4-0, 6-0 in the league and broke the record of points (Highest La Liga point ever) and goal record, they were one of the best counter-attacking team in world ever.
With our budget, we are not going to spend much more money on attacking for no reason if we are not going to strength other weak position.
