Again and again, Madrid lost their momentum as today's match saw them pick up just 1 point with some drama in the match.
Jude's red card was one of the things that did affect the quality of attack in this match and indeed 1 point is still quite good than nothing at all, it's just that with this result, Barcelona's chance to top the standings is very large now.
Madrid are lucky because Atletico are also not doing well but for now they clearly have to wait for how Barcelona is competing whether they can maximize this advantage or not because if Barcelona manages to get 3 points in the match in their 24th week then they will automatically be at the top even though they have the same points but they excel in goal productivity later.
