Yes, you are right, so far, the most closed rumor to sign for Arsenal is Gyokeres after their successful signing of Zubimendi earlier. The agreement clause is around €65 million ($76.6m) based on the article that I read and this is so closed for done deal. Additionally, besides Gyokeres, Arsenal is also still working on negotiations with Real Madrid to sign Rodrygo closely, they also want to get that right winger to be on thier player lineup. Moreover, Real Madrid and Xabi have given the green light for Rodrygo to leave, as long as the fee is in line with their expectations. However, they are also facing challenges because on the other hand, rumors also say that PSG also wants him.

After having four failed attempts to win the league, this is what I expect them to do, strength their depth especially the attack. If you notice, Arsenal has one of the strongest defense in the league if not the strongest so they're okay in that area, I love how they're going after attackers in this summer transfer, not just attackers but world class attackers and if they succeed then this season would be Arsenal's season. Arteta should try everything possible to break that ill luck this season, he's a good manager but just so unlucky, I hope he succeeds this season cause this time around ending the season as runners up might not favour him, not only fans but the board would start thinking of a replacement.Reference: https://www.football365.com/news/arsenal-dream-target-rodrygo-man-city-liverpool-gyokeres-checks-in-bags
