Hm. I'm not sure how much comfort you can take from this result, Pix, to be honest. Everton look like a team that wants to be relegated, and Koeman is clearly a manager who is not going to make it to the New Year. I think you need to see how the next couple of weeks pan out before giving it large, mate. You don't want to make yourself look foolish, again.
Normally Liverpool do well in these games but without Mane think they won't be as effective. Plus, it being at Wembley Klopp might think it's a cup final and go into automatic defeat mode
Imagine not only getting subbed 30 minutes into the game, but to get replaced by Oxlade. It would have anyone reevaluate their career.
