The concerns for me about Sesko is that nothing in his career so far has shown him to be prolific or magical.
There are plenty of players like Havertz, Wirtz, Haaland etc. who are and were completely getting consistent league output in their position at that age. Considering Sesko is 22, he's getting similar league goal hauls to Wirtz and less league goals than Havertz who weren't even playing upfront at the very same age.
We're paying top dollar for a player who is all potential and expecting him to be the difference in the blunt attack or wasting another league season.
People don't understand how important this window is - We're at the cusp of testing the patience of players like Saka, Saliba and Rice who will start looking at their options if we don't win anything next season.
Saka in particular would be 24 turning 25 with 300+ appearances if he goes injury free and nothing but an FA cup to show for it. Exactly the same age and appearances like cesc when he finally lost patience in the project.
