Can't agree with you there.
Realistically we would be in the market for a maximum of 3 players in this current transfer window - not enough to make a massive difference apart from gaining an effective top drawer striker, although there are precious few of these on the market at the moment. So not much moulding available on that front. The transfer ban (discounting the winter period as that's a waste of time at the best of times) is a relatively minor blip in the long-term road.
We still have a deep and strong squad with a huge opportunity to mould the playing style (again!) although realistically that's going to take c 2-3 years to achieve - so plenty of opportunity there.
By all accounts there were a number of top flight managers that were open to consideration for the role - ultimately a salary of up to £12m pa (& maybe more for a
top top manager) to manage a Top 4 EPL team playing in the CL next season is pretty tempting package. Only 3 managers in Europe currently earn more than that.
I'm thinking that Roman is trying a different route on this occasion and I hope it works as, despite a quite successful last season, the football, which was great for the first 18 EPL games, then stagnated into an utterly miserable, possession based game that had no teeth that was dire to watch.
