So there's the assumption that I take issue with. Nobody says he has to have played 50 or more games for us. But keep him in house and let him compete with White, and see who comes out tops. I have no doubts whatsoever that he would have been seen as a first team option sooner rather than later, and we wouldn't have had to suffer games with Rob Holding as our only available partner to Gabriel or move Xhaka to left back or whatever contortions Arteta was having to perform last term.
Again, if it was Arsene in charge there is zero chance we loan out a talent of this magnitude to "protect" him. The protection bit is overrated also. We watched Gabriel make his mistakes, get his red cards, and learn from it and move on. We watched Ben White in his first game against Brentford get torn to pieces, and nobody crucified him either. We didn't make any moves to recall the kid from the loan in January even though he was tearing it up in France pretty much from day one, and everyone there was raving about him. Instead we had to put up with Holding and Mari and eventually Xhaka playing in the backline...
What frustrates me about this "debate" is that it's actually quite clear to me that we could have and should have handled it better and kept him in the fold. Forget about Arteta. Someone else has to be able to see the talent and point it out. Imagine having an option to have a budding Fabregas last season, but then loaning him to Rayo Vallecano or wherever, saying we needed to protect him because midfield is so sensitive and if he lost the ball there people would not forgive him, and besides we have Xhaka who is more experienced, blah blah blah. It's just ridiculous. If talent is good enough it is old enough. And it's up to the decision makers at the club, notably the head coach/manager to recognize it even before everyone else does, and make the right call. Why is this even slightly controversial?
