Even if we exclude the extraterrestrials Ronaldo and Messi, in the last 10-15 years we saw some amazing strikers who shined in their mid to late 20s. From the top of my head: Ibrahimovic, Lewandowski, Suarez, Van Persie, Benzema, David Villa, Cavani, Aguero, Drogba, Higuain.
Who do we have now from the strikers aged 25-30? Lukaku is someone I like and I consider a top striker, despite his many missed chances. But who else is there? There is probably someone I'm missing because I find it impossible that there are no top strikers in the world. We say that we want a top striker, but what's the choice realistically? We either go with one of the former greats or take a risk with some teenager who shows promise. And apart from that Norwegian kids, what's the choice?
Strikers are a dying breed
P.S: Griezmann too.
