Based on how Monchi did at Roma, and to a lesser degree how he's done since he's gone back to Sevilla, its maybe for the best it didn't happen. Technology has moved on, and all the big clubs now know the form of every highly rated 15yo in South America and around the world, and with the use of feeder clubs can keep them away from the competition in case they turn out to be the next Zidane or similar. Its ruining the game, but neither UEFA or FIFA care as long as the bungs keep rolling in. So the model of clubs having a big team of scouts roaming the world like Monchi used to have is pretty much dead.
That article from Brands is relatively standard for failed DoF/Scouts. "I recommended all these players who turned out to be great for other clubs, but it never happened", but they don't mention the other 100 recommendations they also made that turned out to be crap for other clubs and the 30 players they recommended we sign, and turned out crap for us. The arguments about whether Silva should have been sacked or not are easy to make now, but at the time there would have been a riot if he'd been kept on for much longer. He'd lost the squad, and he'd lost his head, and giving him an extra month or two was only delaying the inevitable. He needed to be put out of his misery, and to significantly change the trajectory of results it made sense at the time to go for Ancelotti rather than Arteta. The time Arsenal have given Arteta to turn things around wouldn't have been given to him with us based upon how quickly the improvement needed to happen. Ancelotti was always likely to leave as he did, but he left us significantly better than he found us.
Don't get me wrong, I think Brands did ok in general, but equally that he wasn't snapped up by someone else before/after he was forced out, and has just returned to PSV is a sign that maybe he hasn't the capability or credibility within the football world that he thinks he does.
