Matthias Sammer has questioned whether Jürgen Klopp can impose his ideas on the German national team as quickly as he did at club level, speaking during Germany's latest training camp.
Sammer outlines concerns on "Sky"
Speaking to "Sky", Sammer, who lifted the European Championship trophy in 1996, discussed the scale of Klopp's task during the current international break.
Sammer said: "I think the matter is extremely difficult for him at the moment, because his great strength lies in daily work and developing players in the way he wants to play, but he does not have this time now".
He added: "He is not yet able to transmit his full strength as a national team coach, compared to his stints with clubs".
Sammer also stated: "I cannot expect much at the current time, as the direct impact that Jürgen always left when he was a club coach is not yet possible, and therefore I think the matter will take some time".
Early phase of Klopp's Germany tenure
This is Klopp's second camp since taking charge of Germany. During this international window, Germany are scheduled to play two UEFA Nations League matches.
Germany travel to face Serbia on Friday 13 November, then host the Netherlands in Berlin on Monday 16 November.
Review of September results
In September, Klopp beat Serbia, lost to Greece in Augsburg, and drew twice, with the Netherlands and against Greece in Thessaloniki.
Change in squad size
Klopp is working with a 24-man squad this time, having handled an expanded list of 44 players during the previous exceptional camp.
