Highly unlikely that ATM beat Madrid again. On top of it, I think Manchester United have a chance to sign Alvaro Morata before the transfer window ends. Barcelona, even though they are in financial trouble, they are also a threat for the title but in the end, I think it'll be Real Madrid to win for another season.
Madrid does seem to be without a burden for this season. they are still reinforced with a strong team. whereas Barcelona has a burden on its finances. although it seems fine with bringing in some new players, I'm not sure Barca's financial condition will be fine until the middle of the season. This can make the player's performance not good.
but to annoy Madrid, I think Barca has that ability for now. their squad is getting better for now.
