A throughly entertaining game ends level at half time in the tie, although Dortmund have two priceless away goals for their efforts. All four goals were avoidable from a defensive point of view, but both teams showed glimpses of their attacking potency, and in three weeks time the second leg in Dortmund promises to be a cracker. Thanks for your company tonight and I'll see you all soon.
