So sending Beckham to Preston NE to experience the 'mens' game was bollocks, even Beckham himself admits his stint in the lower leagues improved his technical ability. By sending a youngster out on loan to play first team football you are doing two things proving that the individual can adapt to a different style/level and making a point to them that just because they start at a big club doesn't mean they are good enough to stay there. U18 and U23 level is all well and good but it is still very much a goldfish bowl for young players. Not all loans work out it is true but better for a player and a club to find out sooner rather than waste more money on what may never happen.
Well done, you've literally made the exact point I was making. It was the right loan for him, rather than simply saying physicaility was outright a blanket good thing.
