I can see the theory, bolster the defence and leave one man up as the outlet. Regrettably that one man up top was Chamakh so that effectively reduced us to 10. Taking Theo off and replacing him with Frimpong was a stupid substitution but not overly damaging. However taking Gervinho off and bringing on a full back, WOW, that's a thick as it gets. Dortmund gladly accepted the invitation and almost won it in the end. We have a terrible manager and terrible coaches.
