I think Janko, M.Keane and Lawrence will all become handy squad players....one out of them may become a first teamer one day but it's hard to say.......Wilson looks great too and could have a huge future but it will be a long time before he gets anywhere near our first team......a couple of years ago the likes of Larnell Cole, Tunnicliffe, Lingard, Daehli and Will Keane etc were being hyped up as certainties to make our first 11 eventually and it never quite turned out that way
Not by anyone who knew what they were talking about. No player is a 'certainty' - not Morrison/Pogba, not Januzaj, not Wilson.
Cole, Lingard and Tunnicliffe have always had as many detractors as supporters (in terms of their chances of making the first team), as I remember it. Tunnicliffe in particular was regarded as less and less of a solid shout as he got older, because more and more people saw that his technical ability was not keeping up with his other attributes. Lingard, I maintain, still has a chance of making it into the senior squad. He's shown in two tours in a row that he can be special when surrounded by top players.
Daehli was definitely regarded as up there with Pearson and Wilson as a possibility, but then he never had the chance to
not make it, did he? He wanted to leave for first team football, and we let him. He certainly didn't leave because anyone didn't think he was good enough - he'd been developing very nicely.
Keane is the only one where you really have a point. He was quite literally the Wilson of the generation before. But he's living proof of how much a badly timed injury at youth level can hurt you. It's not just about delaying your development, but about other younger players accelerating past you. I couldn't tell you what will happen with Keane, but he's certainly missed his chance of getting first-team game time via the short route.
I agree with your basic cautionary point, but I don't think it's fair to make out that the Caf's youth forum as a whole ever got unduly optimistic about these players. There are always one or two getting overexcited, but in general the consensus on here is sensible, because it's formed by people who watch youth football week-in week-out, and know how quickly a promising player can make it as a first-teamer, and how quickly they can disappear into obscurity.
