Many will remember Kramer as the player who was a late replacement for Sami Khedira in Germany's starting lineup for the World Cup final, only to receive an early knock to the head and be forced off the field with concussion in the 31st minute.
Is Kramer the right fit for Napoli?
Though he was not able to make much of an impression in the biggest game of all due to those unfortunate circumstances, he has built a reputation in recent seasons as a midfield engine who brings a great deal to the table.
There is contact with Napoli. The offer is interesting, especially because Rafa Benitez is the manager and he is a great coach.
At the moment I cannot say anything else. I could go back to Borussia - there are many possibilities.
Fenn also points out the the 23-year-old's contract with Leverkusen expires in 2015, making a move away all the more likely. If the club does not sell or renew before the end of his contract, they will miss out on any profits for the player as he will be allowed to leave for free.
Napoli already have a strong midfield, with some depth too, but several of the more defensive-minded players are reaching the latter stages of their respective careers.
Uruguayan Walter Gargano is 30, as is the multi-functional Gokhan Inler. Key midfielders Blerim Dzemaili (28) and Valon Behrami (29) are approaching that age as well.
Bringing in a world champion youngster who has already demonstrated that he possesses a strong personality and winning attitude will not only serve to revitalise the squad, it will give the team a solid base to build from in the years to come, as others move on.
Kramer's energy and toil would prove an asset to any side, and his technical ability on the ball is at the standard you would expect from the current crop of German internationals.
In short, he is a Benitez-style player and should fit in very well at the Southern Italian club, if they manage to sign him up.
