Arsene Wenger made it clear that he was going to stick to his strategy of finding bargains on the market when he sold Robin van Persie to Manchester United this summer.
He continued to sell when he transferred top midfielder Alex Song to Barcelona.
Even with summer acquisitions Lukas Podolski, Olivier Giroud and Santi Cazorla, there was unrest at Emirates after Van Persie and Song left.
Sahin is an excellent midfielder who will combine with Cazorla to make up for Song's departure. Ever since lifting Dortmund to the 2010-2011 Bundesliga title, he's been highly regarded in world football. His precise passing, combined with his sterling vision, sets Arsenal up to do some damage with strikers Podolski and Giroud.
Has Arsene Wenger done good work this summer?
Cazorla, Podolski and Giroud failed to produce a goal in Arsenal's Premier League opener against Sunderland on Saturday, but the offensive unit did show some promise. The Gunners got off 23 shots and possessed the ball for 70 percent of the match, but failed to make their shots count.
Given the talent level of the three summer acquisitions, it's very likely that they start creating some goals after they mold together. The acquisition of Sahin makes it even more likely.
Sahin is just 23 years old and still realizing his potential. He could be in for a breakout season with increased playing time at Emirates. In fact, this was the perfect time to acquire the budding midfielder.
Just when you think things are going south for Arsenal, Wenger pulls off a tremendous deal.
