It is really embarrassing for Liverpool to be beaten by every team after they have won the league title. Such matches may not be too important for them towards any trophy but clubs uses those matches for their records. Apart from that, the fans also use those matches to cheer themselves up, get motivation to buy tickets and even bet among themselves. These are the things that makes the sports fun and bring out that pride of supporting a club. Liverpool should have a change of mindset for their remaining matches so they can bring some excitement to their supporters.
But things like this are quite common, not just this one time, as seen by Liverpool. But in other leagues we often see teams that have already secured the title starting to get lots of bad results in the remaining matches of the season. All of this is because sometimes teams that have secured the championship title no longer have high motivation to win the match. And apart from that, coaches often give time to reserve players to be able to appear in more playing time. Meanwhile, the main players will be given more rest time. And sometimes teams that have already confirmed themselves as champions will consider the remaining matches as matches that they can use to test several new strategies. So I wasn't surprised by Liverpool's defeat by Chelsea.
