We don't get a lot of penalties, I don't see that changing.
Can't really judge who will outscore who from the pair but to be fair I am not overly certain either Lacazette or Lukaku will score over the 20 goal line. Last season aside, it is a very consistent trend in the current EPL history that only 3 players top the 20 goal mark each season.
I think one of that top 3 spots is reserved for a City player. Whether Aguero, Jesus or Sanchez , they are the team with the goals in the EPL.
Another spot goes to Chelsea, who I think might be champions again. Whether with Costa up front or someone else, they are a classic case of a team who relies heavily on their main striker to get the majority of goals.
Kane has been 20+ striker for 3 consecutive seasons and I can see that trend continuing. Spurs rely super heavily on him and Alli for goals and it's either that or their season will be complete and utter shambles.
Liverpool play damaging attacking football but they distribute the goals across so many attacking players I don't see anyone from there pushing for 20. And they lack the classic striker figure so there you go.
I don't think United have improved from last year. They replaced Ibra wilth Lukaku and I think you have to really dig deep to make a case of improvement here. They struggled for goals so badly last year, I can't see Mourinho turning this around overnight. It will be Lukaku who will bang in the goals for them, that's for sure, but he will fall well short of 20 imo.
We.... We have had 3 20+ strikers in the past 10 years. Sanchez (24), RvP (30) and Adebayor (24). Imo it will take some feat for Lacazette to beat that number in his first season.
And there's always the chance some average striker will have the season of his life.
