DORTMUND, Germany (Reuters) -AC Milan were frustrated by a disciplined Borussia Dortmund as their Group F fixture in the Champions League ended in a cagey 0-0 draw at Signal Iduna Park on Wednesday.
The result was Milan's second draw in the group, following a goalless match against Newcastle United, while Dortmund earned their first point of the campaign after a 2-0 loss to Paris St Germain.
