It looks like Gyökeres is on his way to Arsenal! Recent news say that there is a big progress made lately. He is already looking forward to signing for them. It's all about agreeing on the fee with Sporting now.
Earlier he was really frustrated with Sporting chairman because of demanding a very high sum. I wonder if the situation is still the same...
Unless he turns out to be like Nunez in the PL, Arsenal will increase their chances much more for trophies.
