Liverpool midfielder Emre Can has been asking himself tough questions after Germany's under-21 European Championships exit.
Considered among the favourites to lift the trophy after reaching the semi-finals, Germany were thrashed 5-0 by Portugal, with Can unable to compete with Sporting Lisbon star William Carvalho.
The former Bayer Leverkusen man had been enjoying a solid tournament through the group stages, even scoring in Germany's opening game.
Speaking to German channel Sport1, Can has questioned whether he started believing the hype which had followed his early impressive start.
He said: "Today did not give anything, maybe I thought, I'm the greatest."
Making such an admission especially on a national stage is rare, but in many ways it's an example of why the under-21 tournament exists, to aid player development individually as well as from a FA perspective.
Can will have learned a tough lesson, which will stand him in good stead for Liverpool, a club which is so well supported and admired globally, that the highs and lows will be emphasised.
The midfielder added: "It is not at all to explain nor to apologize. What we played there, was just a joke. It is a sad day for Germany. I think the holiday will us do very well now."
The lesson learned by Can and Germany could also apply to England, with many players earning huge weekly wages and being discussed as multi-million assets, their failure to get out of the group stages should be an eye opener that much improvement is required.
