The dynamic playmaker has been hailed as one of the best players in the German league, and with his arsenal of skills, it's a wonder how he hasn't been transferred to the likes of Real Madrid or Manchester United.
Sahin, a German-born Turk, splashed onto the international scene when he became the youngest goalscorer in Bundesliga history. It didn't take long to earn a call-up to the Turkey national team, an invitation he gladly accepted.
Scoring against his home nation (Germany) in his first cap, Sahin also became the youngest goalscorer in Turkey national team history.
Modern football insists on dropping a striker for a creative midfielder in the middle of the park. Xavi (Barcelona), Wesley Sneijder (Inter Milan), and Cesc Fabregas (Arsenal) are all prime examples of this.
Let's examine the possible destinations for the Turkish talisman this summer.
1. Manchester United
Sahin's style of play would fit hand-in-glove with Sir Alex Ferguson's 4-4-2; although that may be contradictory to my statement above, Sahin would be the perfect replacement for Paul Scholes.
Anderson has been used in the center of midfield, but the Brazilian attacker is more suited in the hole. The other center mid prospect, Darron Gibson, isn't as talented as Sahin.
Sahin's ability to play the killer ball—one of Scholes' trademark skills—is possibly his strongest weapon. With the added incentive of learning under Sir Alex, Sahin could become world class.
2. AC Milan
Sahin would be a breath of fresh air for the geriatric Milan midfield. With the likes of Gattuso, Seedorf and Ambrosini not getting any younger, Sahin could take the central playmaker role in a 4-3-3. Throw him on the pitch with the likes of Cassano, Robinho and Ibrahimovic, and that quartet would be deathly dangerous.
Anelka looked comfortable in his role behind two strikers, a role he will need to get used to with the addition of Spanish international Fernando Torres. This means Chelsea can stick with a three-man midfield, with one of the three spots currently being switched around with Ramires and John Obi Mikel.
Sahin's ability to control the middle of the pitch could free up Lampard, allowing him to do as he chooses. However, Sahin's physical ability and pace would also allow him to pull out, with Lampard patrolling the middle with Essien.
What About Real Madrid... Barcelona?
Sahin would either be a bad fit or too big a player for any other club besides the three listed here. Clubs such as Barcelona, Real Madrid and Manchester City wouldn't be able to appreciate his entire skill set.
Barcelona have their own system in place, while Madrid and City are plainly too overcrowded at his position. Another avenue could be Tottenham, but they also suffer from collecting too many playmakers.
If Sahin does indeed leave Borussia Dortmund, his new club and manager will be lucky to have him.
