I still find it difficult to understand what you are saying because apart from a couple of games that Real Madrid played draw I don't think they have really dropped in form and saying that Ancelotti has been without improvements for about 4 years now sounds very complicated to me because for this 4 seasons you have mentioned, Ancelotti has done exceptionally well for Real Madrid. The only thing I can say about Real Madrid's game against Deportivo Alaves tonight is that Real Madrid at this time may not want to gamble their chances in the league table since they are already 4 points behind Barcelona who are already topping the league table so i expect nothing from them than to win Alaves and claim all 3 points because they have all it takes to win Alaves without struggles even though anything can still happen in the end.
Real madrid got an early lead from Lucas Vázquez in a minute of kick off, assisted by Vinicius Junior though it ought to be a two goals lead by now but unfortunately it was ruled out by the referee as offside from Mbappe who scored the goal.
I think Real Madrid would win especially from The fact that there have been a good link up play to the attack notably the ruled out Mbappe goal
