We thought there may be goals and there have been chances aplenty for both sides but some excellent goalkeeping (and the odd miss) means it is goalless at the half.
Both sides have attacked well during the first half, with Dortmund in particular looking extremely lively. Of the two, City have looked the less composed at the back with Joe Hart rescuing them on multiple occasions late on.
City, in particular David Silva, have attacked well at times but have found their path blocked by a resolute German defence. Yaya Toure has played a reduced and more defensive role and with Javi Garcia having been substituted through injury, the chances of him pushing forward later in the game have reduced.
All set then for what should be an exciting second half with all to play for.
