I'm not sure culture has really changed since SAF's days, many of our fan base still think we should accommodate players but ignore the fact the quality around those players has steadily fallen, there's a reluctance to accept we haven't been a regular CL team for a while now and that we can't just sit in and counter as a tactic.
If ETH is sacked and the Glazers stay I don't really know what will change but the least we should do is hire someone who is hands on and has coached a high press team in the PL before - that's such a low target in truth for the size of club we are - but I think it's where you start. So yes an 'unflashy' manager would be important for me. Someone who has built something on a budget and been able to form a team that could take points off the biggest teams. Every player has a role, no player gets carried, we move on the older names and start to drastically bring down the average age of the squad. We become a fast, aggressive and high energy team who people hate to play against and move away from the bigger name players. it's about time we started creating great players again instead of trying to buy them.
