There are loads of gems last few seasons, Kante, Keita, van Dijk, Mane (when he moved to Southampton), yes there is a real buzz created when the club do sign a superstar, but I'm much more satisfied when the club unearths a class act for peanuts (Hyypia) or even better a player comes through the ranks to be top class (Fowler, Owen, Gerrard, McManaman or Carragher).
Jurgen focuses on the latter rather than the former.
As far as signing class players for peanuts,
Matip on a free has to be up there, though perhaps not entirely unknown. A couple of years from now
Gomez for £3.5m and
Grujic for £4.25m might look like absolute steals as well... and so too might
Karius £4.7m if he fulfills his potential (23 is still very young for a goalkeeper).
And don't forget about
Allan at £500k. One more year out on loan and he'll probably come back and be a nice little feisty addition to midfield.
Granted, most of those aren't exactly "unearthed", but does that really happen anymore these days when everyone and their dog knows about Fulham's 16 year old leftback?
As far as players coming through, it seems as if the academy is finally producing some quality players again (especially Woodburn, Wilson, and Trent) - with Trent probably the most likely to be a regular fixture in the first team next season (as backup RB).
