Arsenal have been here before. The present and fierce debate over whether they should sign a striker in January is similar to the mood around the club three years ago, when Pierre-Emerick Aubameyang was abruptly transferred to Barcelona and the Gunners pondered signing a replacement.
Steadfast in their belief that the ideal player wasn't available, Arsenal decided that they would not compromise or gamble by pursuing an alternative, instead trusting those already at the club to see it through. They ended up paying a high price, missing out on UEFA Champions League football by just two points as late-season defeats at Newcastle United and Tottenham Hotspur cost them dearly.
