It's not always about quality. Gnabry would fill a certain void in this squad which really needs to be filled and should, imo, be the number 1 priority this summer (if we continue the Sanchez as CF thing). A quick, technical proper, forward player who can combine and has goalscoring potential. When with Cazorla and Ozil in the squad, signing Fabregas might just have been of lesser priority. Since this club is so slow and reactive on the transfermarkt, letting him go when you got him, was a mistake.
