All the morning news and gossip from The Emirates Stadium.
Dortmund took an early lead in the game via Henrikh Mkhitaryan, the former Liverpool target benefitting from Marco Reus dispossessing Aaron Ramsey just outside the penalty area.
But Arsenal were playing well, and when Olivier Giroud beat Roman Wiedenfeller to a Bacary Sagna cross, he was left with the task of smashing the ball into the back of the net for 1-1.
However, as Arsenal pushed on late for a winner, Kevin Grosskreutz charged away on a flowing Dortmund counter-attack before his lofty cross found Robert Lewandowski at the far post, who placed a volley beyond Polish team-mate Wojciech Szczesny to earn Dortmund a hard-fought three points.
Napoli beat Marseille 2-1 in the other tie, meaning that the German, Italian and English outfits are all now tied on six points after three games - Marseille are bottom with zero points.
Jack Wilshere came off in the game, and was then spotted with his foot heavily iced on the subs bench. But speaking to Sky Sports he claimed it was nothing to worry about, simply expressing he jarred his ankle:
"I'm alright. I just jarred my ankle.
"I have done it before and it's painful for the first minutes or so, then you can run it off and I'm alright at the minute."
Concern was obvious considering the major injury issues he has had, including those in his ankle, over the past couple of years.
‘’We put ourselves on the back foot with the first goal and were naive for the second... We can only look at ourselves as not being mature enough in those situations. If you can't win the game, don't lose it."
Clearly the Arsenal boss was unhappy that his team had lost on his 64th birthday.
Finally and Fernando Llorente is reportedly up for a move to Arsenal in January. The Spanish international is currently struggling for first-team football at Juventus, after spending most of last season out of favour with Athletic Bilbao.
He now wants regular football in order to make the Spanish squad for the World Cup in 2014 - and is willing to go out on loan to achieve his dream.
