Allan and JR were signed because the club has ambitions to qualify for Europe. These are the ambitions of the owners, and Ancelotti's ambitions. The fact that some fans have less ambition does not change this fact. We can discuss indefinitely whether this is realistic, but the club has considered it to the point that this is possible, and has therefore invested in players who will give immediate success.
Personally, I think this is a risky strategy, and would rather think more long-term, and gone for other player profiles, formed a foundation that we could gradually build on season by season. The club considered it differently, and has invested in JR and Allan to achieve this as soon as possible.
These are the two top players in Everton, and who will give us the necessary quality. Both are unfortunately frequently injured, and their curve is pointing downwards. Yes, I'm skeptical of the strategy until it is disproved. This means that we qualify for Europe, which is the club's goal. If you do not achieve the goals you are aiming for, then you have failed.
