Yes, Atletico Madrid has great potential to interfere with Real Madrid's chances of defending the title. My prediction this season is that the La Liga title race will be competitive again, even though many people still favor El Real.
It's still too early to say who can compete with Real Madrid in La Liga. Atlético start the last season also not bad, but then even Barcelona, which had a very difficult season, managed to get ahead them. So far, Real Madrid looks like the favorite for me, and in order not to get too far ahead, let's look at Saturday's match against Celta. I think that it will not be a problem for Real Madrid to beat them for odds 1.7, which is not bad at all.
