Carlo Ancelotti was the last guy that took them to champions League, that was before xabi Alonso came in some few months back and took them the club world cup. There's no doubt that Xabi Alonso is experience but the technicality that is required in Real Madrid this period needs him to think way deeper, first their performance in the club World Cup was a mirage, it was below expectations and the leakages are still there. With the way Barcelona is formidable this time around with Lamine yamal, trust me Madrid are going to get a serious fight for the title this time around.
Barcelona just coped Marcus Rashford on a loan deal, in a bid to strengthen the team, Madrid has to understand that the rivalry next season is going to be strong suc that they may stand a chance of loosing out in both the la liga ans champions league if they are not rapid with their improvement, I understand xabi needs ti.e to realign the team to a formidable form but at the same time he also needs to hasten up with it because the season will not wait for him before it begins. Rashford may not sound like a threat at the moment but remember when he was in his prime at Manchester United, he may be reawakened in Barcelona following the mentality been used there and then we may see some reason why Madrid needs to sit up when the yamal and Rashford combo sets in at their prime.
