The academies in Germany and Spain are for the most part superior and thus producing a higher number of talents, but I feel that in not trusting their youngsters English clubs are missing out on some really good players, because they don´t get a stage to prove themselves.
Not every youth player shows his true strengths right away and can really sursprise when giving actual play time.
A German example for that is Jonas Hofmann. In his youth career he hardly sticked out, only making a couple of games for the German U18. He was scouted at Hoffenheim in 2011 and brought into the reserves of Dortmund, where he played the last two years. Klopp gave him a couple of minutes in the first team last season and saw potential in him. As result he pulled him up into the first team and actually commited to him. A lot of people expected Dortmund to sign an additional player for the offensive midfield (4th or 5th option) and the heaviest linked player was actually Eriksen. It became clear sooner or later, that they did not plan to do so, because Klopp had no intention to take away Hofmann´s squad place.
And from the look of the season so far, Hofmann is on his way to repay every bit of the trust he was given. He already was vital in one league win and gives his all in every minute he gets. This is something that I see a lot in young prospects. They truly work their asses off on the pitch, because they know that they need to prove their worth and don´t take their chances for granted.
Coming back to Eriksen, I really think that he is overhyped in general and on here aswell. I have seen a lot of him in the last season, because of the supposed interest of Dortmund. He has games, where he looks like a world beater but at the same time, he often dissapears in games, especially when he gets little space. He really lacks consistency so far. Right now, I certainly don´t see him walking right into Tottenham´s starting XI. He will have to really earn his place there.
