We will be fine. We have a better squad than the team that finished 7th last season, albeit without Lukaku. A good manager will whip them into shape fairly quick.
Lessons must be learnt though. I hope there will be an inquest into how mistakes we're allowed to be made, especially in terms of recruitment.
Bringing in too many players at once, and failing to replace Lukaku and a center back was criminal.
The blame rests squarely at the feet of the board. They are the ones who recruited Koeman and Walsh; a tactically sub-standard manager and a glorified scout.
