Because I know the players.
The Dortmund star told Swiss daily Blick: "I would have been happy if he had joined us". For two years I have trained with the guys.
If I join Unai Emery's staff, I think it should be good for me, and I hope it should be good for Unai Emery.

With the appointment of Unai Emery, the incoming transfer business and speculation surrounding Aaron Ramsey, the future of Jack Wilshere has somewhat been forgotten.
"I don't know what will happen in a couple of months, but if I can train with the guys I will, because for me it's very important", he said.
'With Arsene Wenger it was easy to keep fit and to still train with the first team.
We've already signed Stephan Lichtsteiner from Juventus on a free transfer but the 34-year-old is only a short-term solution so we need to think to the future and it looks like Emery has a target in mind.

"If you see the players, if you see the club, the stadium... it's the project, the big opportunity to get back to the highest level". Because for such a long time it was Arsene Wenger.
The BVB defender has no doubts about the quality and experience he brings to the table and believes his ability to put in consistent performances makes Lichtsteiner a special player for any club to have.
