I've been giving this some thought (the comparison between this relegation battle and last season's).
I actually think we've forgotten just how desperate it was last season. In the end we were reliant on the wheels falling off a resurgent Burnley to stay up. We looked gone until they started to sputter with 4 games to go.
And although the Richarlison 'difference' to last year compared with this is a factor, we conceded a PL worst ever total for us which landed us in it last season and we have better GD right now than last season.
5 and 6 games out last season we were in the bottom three and needed a small miracle. And we got it with unlikely back to back wins against Chelsea and Leicester. That was a much gloomier moment for us than now.
As I keep on saying the dynamic was different last season.
Norwich and Watford were basically gone at this point so only had to avoid one relegation spot. Don't think Norwich or Watford even got much over 21 points that currently Bournemouth are on with just under half a season to play.
Team were pretty much in the position Palace are in now. 4-5 points clear but hadn't won for ages. Then of course Burnley won a couple and panic stations set in.
I actually wonder what would've happen if the Burnley away game had stayed at 2-2. Losing that felt the end of the world but it actually did spark the team into realising what was going to happen and the end of season was pretty good with all the games bar Watford away that needed to be won were won (and surprise results like Chelsea at home).
This season the dynamic is totally different as 19th-20th could easily finish above 17th-16th and many of the run ins have a similar look. Southampton could I reckon win 4-5 games in the run in which wouldn't be great at all.
Add in lack of quality in final third compared to 12 months ago with Richi and Gordon playing huge parts in the run in and I agree with the post above, can see draws and the odd 1-0 win but I just don't think it will be enough this season.
