we finished 5th last season and I actually think we are weaker as a team.
this is assuming that Sanchez will not stay.
Lacazette will be good but he won't get as many goals as Sanchez did. I think we bought him just to fill the gap of Sanchez's goals.
However I do expect Xhaka to be brilliant this season and the other new fella will be good. We may re enter the top 4 but will be more of the same I reckon.
