I dont think Palace is standing still. I think the club is not maybe progressing as fast as many would like but you do have to be realistic. The higher up the football pyramid you go the steeper it is and the slower the progress.
We football fans have short memories and are very fickle. Before I say this I too get bored of people making out Parish can do no wrong because he was part of a consortium that saved the club but whether any of us like it its a fact, he was. Rewind back to 2010 and we were on the brink of relegation to the 3rd tier of English football. Somewhere we haven't been since the 1970s. Forest, Wednesday, Leeds, Birmingham, Newcastle, City, Southampton have all been there more recently than Palace. Building on that particular bedrock the squad was rebuilt, the stadium was improved as best as can be done within its current structure (I never go into the Arthur, I'm told the toilets are still like something out of Game of Thrones) but the point is they are trying to push forward and compete both on and off the pitch with clubs that have Billions and reside in stadiums Palace could only dream about.
The club invested heavily in the academy which will 100% bring talent into the first team but it takes time. The club does not have 100m or even 50m to spend on a single player so they have to scour the globe for young talent (Franca) and bargains (Lerma) but this takes time. The club cannot afford 50m players in the squad to sit on the bench so the club needs good coaches to work with the best talent we can afford, and yes our second string is currently not good enough but it takes time. The club desperately needs to redevelope the stadium. In London right now where we have a mayor that quite literally wants to charge us for the air we breath and a NIMBY living nearby in every direction, not to mention a Supermarket on site (Raymond Bloye's fault not Parish) that keeps driving the price up on an essential but small piece of land, again, none of us want to hear it but it takes time to sort out.
I personally wonder if the stadium situation will ever get sorted but if you try and look at the positives instead of the negatives we are what we all dreamed of being in the top division. Competitive. Dont try and tell me its a fluke we have survived this division for ten years without relegation. Its impossible to stay in this division for even 2 years on luck never mind ten. We have probably the best first eleven that we've ever had (and thats without Zaha), we still have Olise, Franca and maybe even Ferguson to yet enter the fray.
No one would argue that progress is at a snails pace sometimes but personally I think in this division? Considering what we're trying to compete with? Standing still is progress.

Problem is we just don't invest in the team enough
Right back we need an upgrade and left back needs competition, Centre back's are fine just get rid of Tomkins, I love our midfield 3 but they need a bit more competition, Olise and Ayew are decent wingers but our failure to replace Zaha will come back n bite us on the behind, we should have atlease picked up a couple of back ups.

We also needed another striker, I just hope we get our injured players back soon. Our last 2 matches we have been a bit rubbish and I can't see it improving anytime soon

No, I'd start with the £20m spent on Hendo

I have been a member before, not that is any of your business, are you some sort of stalker

Hardly. I did report his post saying "I thought Sarf was the most ignorant idiot on the forum, but i think you have taken over as the most half witted thickhead at the present time, and that is saying something"

The mods in their infinite wisdom decided that it wasn't worth taking any action so it looks like personal abuse is now acceptable as HOL slides downhill in it's bid to outdo the BBS in allowing people to insult it's members
