Sorry bro, football is not like that, in football if you are doing well, you will be praised and applauded for it, but when you are performing below par, you will be criticized, which to me is normal in the beautiful game of football, klopp killed the game for his team with wrong substitutions, but congrats to Manchester united for seizing the opportunity.
Concerning the title, I don't really think the title is slipping away from them, they are actually still in the mixed, and to me they even have a friendly fixture compared to their both counterpart, so to me it's Liverpool title to lose, they just have to keep on winning till the last day of the season.
However, don't criticize too much because Manchester United, who play on their own, of course have a large percentage of winning this match, so it wouldn't be a big surprise if Manchester United were able to win and advance to the semifinals.
In football anything can happen and what Klopp does is inseparable from the tactics he uses to improve the team's performance and no one knows what bad things might happen, I think that's quite natural.
