Opposing fans are right to be sceptical. Arsenal fans are still sceptical! It's a work in progress that looks like it's going in the right direction, but there's just no guarantee of continual improvement, & that's true of any side.
A whole amount of variables can happen, new signings not working out, unable to cope with extra workload, injuries, rivals improving, the Newcastle factor etc.
Everyone aims to strengthen, everyone aims to improve, everyone wants more points & to get further up the table, but most actually don't.
Just now, its just good to be enjoying the football again. Things just seen to be aligning a bit, and it's just nice after years of criticism & negativity that while we are far away from a destination, we at least seem to be on the right road instead of what seemed like an endless bypass around it.
