Hans Sarpei says a weak German defence gives Ghana every chance of at least emerging with one point in their crucial meeting at Soccer City Stadium on Wednesday.Germany hammered Australia 4-0 in their first game before they lost 1-0 to Serbia in their second match to leave them badly in need of a win going into the crucial meeting.And Sarpei who plays his football at Bayer Leverkusen thinks there has been a lot in both games that highlights both the strength and weaknesses of this German team."When you see the first game, you see the quality they have in attack," Sarpei told KickOffGhana.com. "But in the second game you also saw how weak they are in defence and that is what we must take advantage of. I think maybe after their 4-0 win they grew a bit big headed and thought they could run over everyone.""But knowing Germany the loss to Serbia will ensure they attach a lot of importance to this game. They will throw everything at us in the beginning but that is where we must stay easy and keep our head calm."Source: Kickoff.com
