We offered 40+4 to Liverpool for Sterling, which dippers deemed serious enough to leave him out of their pre season tour. Then it was negotiated to 44+5. Of course Wolfsburg aren't dippers but still I would have thought neither party would want to risk this deal because of injury
Pre season is something very different to a league match. Plus, Sterling did this interview with BBC. As I already said, a injury would be the best that could happen to Wolfsburg.
