Mikel Arteta has often stressed that the difference between success and failure can be decided by the smallest of details. So, even though Christian Norgaard only started one Premier League fixture as a Gunner, don’t underestimate the contribution the Dane made off the pitch. Obviously, when the 32-year-old left Brentford, he would have assumed he would play more than seven Premier League games for Arsenal. Before the 2012/13 season, that wouldn’t even have been enough minutes to guarantee a winner’s medal. That was despite a proven former Premier League captain being available for selection.
