Serge Gnabry is being linked with a return to Arsenal.
Almost six years ago, following an ill-fated loan spell at West Brom under Tony Pulis, allied with limited first-team opportunities at the Emirates Stadium, doubts were in the German's mind that a long-term role in the first-team would become a reality if he stayed.
As such, Gnabry, with a year remaining on his contract, left Arsenal with no choice other than to sell him to Werder Bremen for around £5million and it's a decision that has regularly come back to haunt the Gunners.
