I am really sad that Liverpool lost against Watford but I am also happy.I am sad because they lost their title of invincibility but I am happy because this suggests that they are fully focused on the Champions League game against Atletico Madrid that is why they didnt play full power against Watford.
I don't agree with you.
They played with full power against Watford and didn't rest any main player.
It's fact that in the last a few weeks Liverpool didn't play well and it was obvious that soon or later they will loose somwhere.
Now they should quickly recover because very soon they will play against Atletico and it's their the most important match in the year.
