A small point gap will always show a fiercer competition until the end of the season because all three teams are still quite aware of their own chances in this season although it must also be seen from the possibilities that can happen to them in the next few matches. For now, all three teams still have the potential to win the remaining matches even though Atletico Madrid is seven points behind Barcelona, but Atletico Madrid should not be written off as a candidate to compete for the title this season because there is still time for them to reduce the points gap.
In conditions like now, only Barcelona and Real Madrid have the opportunity to continue to be in the title race because if you look at Atletico Madrid, they are further behind. Barcelona's victory against Osasuna made their steps a little smoother because now they are three points ahead of Real Madrid who are in second place. With the remaining matches, Barcelona will definitely try to do everything to maintain consistency in achieving victory.
A slightly difficult match that Barcelona will face when facing El Clasico but they are quite fortunate to play at home. Next Barcelona will face Girona but there is not much hope that can be done because this season Girona performed much worse.
El Clasico will determine who win the league between these two teams. If Madrid wins, they have given themselves more hope to win the league. if Barcelona wins, automatically they have won the title. However, if it ends in a draw, Barcelona still maintains their stand. It will be very annoying if Barcelona allow Madrid to defend the title this season, because they have the chance of winning the league currently.
I've also had this thought too that the El clasico will be the decider of who will win the Spanish la Liga, Real Madrid have had difficult times this season in winning Barcelona the last encounters, maybe because the title is involved this time around they will have to improve on their effort to beat Barca. Mere looking at things now, Barcelona are keen on making sure they win the league, the points and goals difference is on their favour, let's just see as things will pan out as more drama will certainly unfold.
