A late winning goal from Lucas Vazquez against Alaves elevates Real Madrid to the top of the La Liga table. Nacho received a red card in the second half. He sacrificed himself so that Alaves didn't score. Down to 10 men, not even playing the best football, and yet Real Madrid wins. Looks like injuries can't stop Real Madrid. With almost 10 first-team players injured, and Ancelotti still manages to be in the first place. First position in La Liga, of course, which is not safe for very long. Hopefully, at the beginning of the next year, Madrid will come back fresher and stronger.
Yes, we could say that Real Madrid's winning goal really saved Real Madrid. After feeling very sad due to only playing with 10 people, in the end Real Madrid was actually able to end the match with a 1 goal win. It's just like luck. Finally Real Madrid returned to first place but with very competitive points.
On the other hand, Alaves does not yet have good enough skills to match Real Madrid. because no matter what, even though it's 11 vs 10 people, Alaves still can't optimize the chances they actually have. So in the end they had to lose these chances and were unable to score a single goal. Judging from their ball possession, there is not much change in them.
