I'm still curiously waiting for who Arsenal will sign for their CF position this summer...
Gyökeres and Šeško are the names stepping forward recently. Gyökeres can actually be signed for a 65 million euros package. But his total cost could still find an amount around 100 million they say. Maybe this is why Arsenal is still undecided about him.

Šeško could also be a great alternative. I don't know how much Leipzig wants for him though. His market value is 65 million now but this isn't the asking fee. I just want to see Arsenal making the right choice for themselves to achieve success finally.
Arsenal got good money from going to UEFA Champions League semi finals this season and for years, a central forward or more exactly a striker position is their weakest position. They perhaps will want to improve their squad with this important position but it's not easy to find good available strikers for sale on the transfer market.
If there are such strikers, Arsenal will have to compete with many big clubs in Europe, and not limited in Premier League clubs. So the race in transfer market is very hot while Arsenal don't have good history like other clubs like Real Madrid, Barcelona, Bayern Munich, Manchester City or Liverpool. It can be a very big factor for convincing such world class strikers to join Arsenal and ignore offers from other big clubs.
Without such top notch strikers, Arsenal will struggle to win big titles like Premier League and Champions League.
