In recent years there haven't been any "roaring" successes,or at least not for us but Chelsea use the buy to let scheme with great success. Ferguson also benefited greatly from loan arrangements the whole way through his managerial career. Campbell has broke into the Arsenal team this year under the same system.
The reasons for our failure have been more to do with a lack of player quality in terms of both our youth players and our signings, and loans are not going to compensate for that.
In saying all that, the youth system has began to turn around recently and we have shown some signs of utilising the loan system better to enhance their prospect. Of the current batch, Canos, Ward, Vigouroux have all got a lot more game time and experience than they would have done here. Not to mention that the academy keepers are getting more game time because Ward and Vigouroux have left.
Jones, Stewart, Williams, McLaughlin were all getting game time until injuries.
Yesil and Alberto are getting opportunities to revive their careers (for different reasons).
It hasn't worked for Ojo, and hopefully he'll benefit mentally because of it. Some of the fans seem to think he was a big time Charlie, but he's young enough to learn from that. Kent has had a mixed season, but it was good experience that he wouldn't have got in our reserves.
We haven't had any world class youngster come through, and if we had they would have likely bypassed the loan system anyway and went straight into the team, like Fowler, Owen Gerrard etc. before them. To dismiss the loan system as a whole based on our failures is short sighted in my opinion.
