RowJimmy they do, but that fact on its own doesn't make them right either.
Tuchel chose not to play Saka I'm the semi and played him the full playoff, there's no clever thinking at okay or was just a stupid decision.
Ultimately I don't think Arteta is a great attacking manager, either he undervalues the things that top level attackers need to have or he's just very bad at judging talent based on his record which has been poor in the attacking recruitment side.
There seems to have been a theme with these types of players Willian, Sterling, and now Madueke. Players that didn't look great before arriving but for some reason he valued them and then they performed in line with what they looked like before joining. Arteta may have extra info available but it's not manifesting in the players greater attacking performance.
