It looks like Ancelotti decided to rather stick to the saying "never change a running system". It might work out for one more year and nobody knows yet for how much longer he plans to stay (unless he gets fired). This year his theory could play out well, but I think next year they will definitely need to make some significant changes. I like Ancelotti though and he deserves the success.
As long as what Ancelotti did works well and leads to success for Real Madrid, I think he will stay a longer time there. So far, the running system that is done by Ancelotti looks good, Real Madrid looks quite strong to be the candidate for La Liga winner or even UCL winner this season. Unfortunately, Ancelotti failed to sign Mbappe, Real Madrid has no new players on the attacking line. But I am very sure that Ancelotti has planned to sign new strikers in the next transfer window. Because I think Real Madrid only needs a bit of change on the attacking line, not on the other lines.
Real Madrid's strength is already very high in my opinion if this coach decides to add more attacking players it might look good but at least it should be considered well because it will increase the burden of costs every month, currently Real Madrid have six strikers which I think is enough and it just needs to be sharpened even better to be the best and always bring victory.
Although the Real Madrid squad has 6 forwards, only Benzema and Mariano are suitable as center forwards. But Mariano's quality is very far
compared to Benzema, even in my opinion Mariano is not suitable to play in the Real Madrid squad. This means that Benzema has no replacement,
so signing a centre-forward should be a priority for Real Madrid. But after failing to bring in Mbappe it looks like Real Madrid have been hit hard
and no forward has been targeted by Real Madrid so far. Moreover, in several interviews Ancelotti said he was very satisfied with the current
Real Madrid squad, meaning that it is a sign that Real Madrid will no longer carry out activities in the transfer market this year. Actually I'm also
quite confident with the current Real Madrid squad, they still have a pretty big chance of winning the La Liga trophy and also the Champions
League trophy. The most important thing is not to get Karim Benzema injured, because Benzema's influence is very large on Real Madrid's performance.
