I'm not entirely sure where I stand regarding such a DoF, and don't know enough about how it really works. As long as he's responsible for premlinary dealings and bringing in coach targets, I'm all for it. But if it's a separate entity bringing in talents just because they're available and have sell-on value, I'm more reserved. Like when we were stacking up on midfielders leaving more important positions unattended. Bringing in players that you know are not good enough for what you aim to achieve is worse than buying players you don't know in my book. Take Gil, I'm pretty sure his technical abilities are up there with the best, how that translates to or is even useful on the pitch is another matter though. If we cannot make use of what he's good at or adapting him into what we need, he's never going to make it for us just because he's a tricky little bugger. I also think that with a few exceptions, a player is pretty much a player, coaching, training, experience, attitude and confidence is what makes a young player good or bad. I think Spurs has a job to do in creating such a (winning) environment, a state-of-the-art training facility with the newest dumbells and so on is not enough.
I also think we have bought and fielded too many ready-made 4th-8th position players, and unless you have a coach with exceptional tactical abilities, that's what you're going to get. If we need an Eriksen, we need to look for a player an with Eriksen skillset and potential, not someone we know is never going to be anything like him just because he's good at something and is available. If we cannot buy the finished articles, City-style, we need to buy and use young talent, forming them into what we need. Like Gareth Bale. WE made him and built upon what he had, when he left he was absolutely nothing like when he arrived. I'm going out on a limb here, but I think buying players like Perisic, albeit being short-term, is kind of like an answer without a question. I get that we're not set up like a Poch/Klopp team or even aim to be like it, but still we need to decide whether we are contenders or in transition. Djed Spence for example, may or may not be good enough to be part of a multiple honours-winning team or the next Kyle Walker (if that's what we want), we don't know, but we know that Royal and Doherty aren't.
