WATCH: There is not an Arsenal fan alive who will disagree with Roy Keane’s brutal analysis

It was all rosy in Arsenal's Allianz Arena garden until the 50th minute.

That is when captain and defensive lynchpin, leader and coordinator Laurent Koscielny limped off with an injury that will want to have been life-threatening - given the impact it had on the game, Arsenal's season and, quite possibly, Arsene Wenger's future. The score was 1-1 when Gabriel Paulista entered the fray, with the captain's armband passing to Kieran Gibbs. Yep. https://twitter.com/Arsestat_/status/832099902440275968 It depends on what you want from a captain. If you want arm-waving anger, give it to Alexis Sanchez. If you want calmness (or boredom) under pressure, give it to Mesut Ozil. If you want someone with an obvious temper in defeat, give it to Alex Oxlade-Chamberlain. Within 15 minutes of Koscielny departing the fray Arsenal were 4-1 down - Gibbs burned on the outside by Philipp Lahm for Bayern's second goal, the armband perhaps slowing the full-back down. https://twitter.com/SportsJOEdotie/status/832127672025227265 Roy Keane was on ITV last night and, unsurprisingly, he homed in on the shambolic defensive display and a perceived lack of leaders in the Arsenal defence. The former Manchester United captain became defined by his noughties battles with Patrick Vieira, Emmanuel Petit, Martin Keown and the rest of Wenger's indomitable, original Arsenal team. To imagine Gibbs setting his jaw when Keane shouts in the tunnel, "We'll see out there" would first require one to first imagine Gibbs threatening Gary Neville, as Patrick Vieira once did 11 years ago. This is an Arsenal team almost completely devoid of the grit, fight and nastiness that made the Gunners Keane's bete noire - the team Keane hated, the team that drove him to be better. This current Arsenal team, which will look to overturn a 5-1 deficit at home next month, can only raise a small out of Keane these days when he discusses them on the ITV couch. "We go back to leaders in the game, being organised at the back. When you're not at your best, you're talking about taking your medicine, when you're 2 or 3-1 down, steady on, stay in the game," said the Republic of Ireland assistant manager. "When I see Kieran Gibbs with the armband on at the end you're in big trouble. If he is your captain, your leader, the guy who is going to bring everyone together, you are in huge trouble. "Bayern weren't at their very best tonight. They didn't have to be - the goals Arsenal gave away... schoolboy stuff." Not even Patrick Vieira would argue with Keano on this one.
