For a guy with an ego the size of Bendtner's, being beyond recollection must be particularly painful.
But the Danish international has long been out the first-team picture at the Emirates, clocking up the air miles and taking in a number of loan spells away from north London.
The most recent of those came with Juventus, where the 25-year-old's reputation took something of a hammering. Juventus moved to sign Fernando Llorente on a pre-contract deal in January, while Bendtner found his first-team opportunities severely limited.
Having failed to score a single goal during his stay in Turin, it comes as no surprise to see the big Dane back at the Emirates with potential suitors in short supply.
Bendtner’s strong sense of self-worth and high salary at Arsenal have proved prohibitive to finalising a move away from the club, but now Wenger could turn to the player in his hour of need.
