I wouldn't say Lampard is out of ideas, more so that his 'Plan A' has unravelled - particularly away from home. I would argue that being aggressive is probably still the right call though because our players aren't capable of parking the bus and not conceding, and playing that way completely blunts our already exceedingly mediocre attacking output - so he doesn't really have that many good choices. I think the Palace game however will hopefully spur him into action for changing much of the personnel though, I hope to see more of Alli, El Ghazi, Mykolenko and Patterson and Branthwaite because I refuse to believe they could do worse than what we have been using.
I tend to agree though that if we somehow cling on this season that we are just simply delaying the inevitable. If we do remain in the Premier League, I think the only way we will be able to overhaul the squad would be to sell the likes of Pickford, Richarlison and Calvert-Lewin all in one go. But I think the club will foolishly try everything possible to resist that happening. As we saw with Digne, many fans are unfortunately still adverse to seeing this squad get gutted too, which makes me worry that we'll see minimum turnover in the summer if we do somehow stay up.
