How about atletico madrid? You know this team has always been in their best performance right from day one of this season which is why they were able to make it up to the top 2nd in the table. And they still have a hope of winning the title because the point difference between barcelona and atletico madrid isn't that much is just a difference of 1 point, so I think the possibility for barcelona to win the title this season is not yet guarantee.
I never said Barcelona has a guaranteed chance of winning the league, I said they deserve to win it.
Also, Atleti have not been in good form from the beginning of the season. They were bad at the beginning of the season but they picked form right when Barcelona dropped a little form. They got above Barcelona but now Barcelona is ahead of them even though Barcelona didn't play this weekend.
Among all the contender Barcelona seem to have Upper Hand of win the title despite the season not ended but staying at the top is also a guarantee because if they can maintain their best form even with the little points gap they can still be the champion. They are still talking the league even though they couldn't have any match in last weekend they have equal point with Real Madrid, by the time they play their outstanding match there will be ahead with three points. The outstanding match means a lot to them apart from getting their three points there will be very happy if they humiliate Osasuna just as they did to them in the first leg.
On the other hand Atlético Madrid really have a huge opportunity to top the table but they failed to do so which was also an advantage for Real Madrid to secured the second place if not there will still be in third place.
As the league is not yet finished, anyone between Atletico Madrid and Real Madrid can most likely top the league and win the title, because Madrid and Barcelona currently have the same points, and even if they play their remaining games, we cannot guarantee that Barcelona will win. However, if the season ended tonight, we are confident that Barcelona would win. However, with a few games remaining, anyone can probably overtake Barcelona in the league and become the favorite to win the league title as well. Let's see how the season goes, but Barcelona is arguably the greatest bet to win the league because they are now at the top, and if they can keep performing well, they will win the title. If they win their upcoming match against Osasuna, they will lead Madrid by three points. And it will be extremely difficult for Madrid to top the league table. Flick understands Madrid's playing style, and when they meet Madrid, they generally win by three points. Let's see how Madrid plays with them in the upcoming leg.
