Regarding the quality of Eddie Nketiah, I think he is a young player who can continue to develop, he is only 25 years old and individually he is quite good.
It seems that Arteta continues to look for players to cover the shortcomings of last season. From defenders, midfielders and forwards. Of course Arteta must work correctly to eliminate big mistakes at the end of the season. For strikers Arteta has got Jesus, he performed well but was not consistent, then Arteta got Kai Havertz but at the end of the season he was also inconsistent. For the rest of the season, Havertz cannot be the solution for Arsenal's attackers. Because that any rumor has it that Arteta is very interested in Serhou Guirassy and Jonathan David.
