Real is playing an away game against 9th Osasuna, which might not sound like a threat, but, given Real's players might have less time to recover after today's game with Man City and the fact that both, Real and Osasuna tend to perform much better at home - we could see a split of points between them. If that happens, either Atletico or Barcelona would take that opportunity and jump to the 1st place.
The results of the next match on matchday 24 will indeed greatly affect their position, whether it will be the same or will change. If one of them, especially Real Madrid or Atletico Madrid, loses, then the ranking position in La Liga standing may change. Atletico Madrid should not have any problems with Celta Vigo. Real Madrid? Hmm, Osasuna is sometimes quite tricky, therefore, Ancelotti must still deploy all of his top first layers. There is no other way to maintain the position other than victory.
And the results of the UCL leg 1 vs Man City this time can be a very good booster for them in La Liga in the next few days.
I am sure Real Madrid will win against Osasuna, although a club like Osasuna can sometimes give a surprise but in the last 2 matches Real Madrid has lost 5 points and of course Ancelotti will not let his club continue to lose points in the next match because the match is very important for Madrid to maintain its position at the top of the standings, Atletico Madrid and Barcelona it is also not certain that they can get full points especially Barcelona who will face Rayo because their opponent is in a good trend recently.
