Think people need to be a bit more patient with their expectations. We should be concerned in 2 or 3 seasons time if the same thing is happening but Moshiri only came in at the end of February when the season was already over thanks to Martinez' incompetence and the weak and fragile players that we seem to have. We have got rid of Martinez' incompetence as a step in the right direction but unfortunately a lot of these players are still the same mentally weak ones that crumbled throughout the past 2 seasons. Let's be honest and fair though, Chelsea just have far better players than us and deservedly swept us aside last night.
If you look at Man City, they were taken over by Shinawatra in 2007 before the start of the 2007/08 season. They came 9th that season having signed players like Elano, Corluka and Benjani, and then Mark Hughes took over from Sven and Sheikh Mansour came in around the start of the 2008/09 season. That season they actually dropped a place and finished 10th but that was the season they made their statement with Robinho, but also brought in Kompany, Zabaleta and Bellamy. Not quite the instant success some of their fanbase would have been hoping for though is it, particularly having splashed the cash on Robinho. The season after they did improve significantly and came 5th in 2009/10 and then established themselves as a top 4 club/title winner in the seasons following that. It took them about 3 seasons to see noticeable improvement, and a 4th season to get themselves in to the top 4.
My point is that although we aren't going to replicate the success Man City have as their takeover dwarfed ours and things have changed, they didn't actually improve significantly until their third season. I'd expect us to be similar. There a lot of players who have been here for too long and sadly just don't have that winning mentality or top class ability and it showed last night. Players like Jagielka, Coleman, Mirallas, Oviedo whilst good players, aren't going to have us going to Stamford Bridge and winning when they have assembled a first 11 with players like Hazard, Costa and Courtois in it.
This season for me is about getting back to where we were under Moyes, a top 7 side, possibly 6 given how poor Man United have been, and then next summer, we can start to try and attract the better players that we were unable to this summer given we came a pathetic 11th place.
I'm in my late 20's so have never seen a successful Everton side, but I have seen a lot of poor ones around the late 90's, and I still think the club is in the best position now since the Premier League era started. It will just take a bit of time to put right.
