wizkid, you've got to be joking ...
Firstly, when you've been around for a number of seasons you notice that at the start of the season, dozens of players are "added" to the national team. This is purely so that the National manager (senior team or U21 team, both do it) can scout a bunch of many players, before deciding upon the best players for the team. Many are called up, few are selected.
Secondly, 5.5M is absurd. That player frankly isn't good enough for the U21 IMO, and he's not worth anywhere near that.
Thirdly, good luck with selling the draftees - but personally, I'm not touching either, sorry.
