What do you mean they have shown they can't hack another season? Mentally? Physically? Liverpool lost the title at Chelsea due to a mixture of inexperience on behalf of the manager, a weaker team than Chelsea, and a bit of bad luck with the first goal. The Palace draw was down to poor defending and again, poor tactical judgement by BR.
So apart from these two games tell me where you think they can't hack another season? They've come 2nd to a team with a world class squad and ended up above a team with a world class squad. They have a poor defence and a weak squad and you can be sure these deficiencies will be rectified in the transfer window.
And the Champions League being a burden? I think any manager would love that as a 'burden'.
