Arsene Wenger changed the landscape of English football forever when he joined Arsenal in October 1996.

The studious Frenchman changed everything at the club, from players' diets to how they conducted their warm-ups. It was to be a period of seismic change at Highbury and it led to one of the most successful periods in the club's illustrious history.

Three Premier League crowns, including one undefeated season in 2033/04, and four FA Cup trophies followed in his first full nine seasons at Highbury, but a period of change saw the club go through a nine-year trophy drought.

His final years brought another three FA Cup wins, but one of his better decisions during his last year managing Arsenal was to sell a player they bought from Southampton for a massive profit…

Wenger’s decision on Alex Oxlade-Chamberlain

Wenger signed 17-year-old Oxlade-Chamberlain from Southampton in 2011 for a fee of £12m and he went on to make 198 appearances for the club, scoring 20 times, a poor return given the number of games he played for the club and his prodigious talent.

Liverpool came calling in the summer of 2017 and Wenger was left with no choice but to sell the Englishman, as he had one year remaining on his contract and it turned out to be a blessing in disguise for Arsenal in the five years since.

The fee of £35m remains the club’s record departure and his spell on Merseyside has not lived up to expectations.

The £120k-per-week midfielder made 133 appearances for Liverpool in five seasons, scoring a grand total of just ten Premier League goals in that period, which means Jurgen Klopp has paid £3.5m per each league strike. With that in mind, it's hardly a surprise to see that his value has plummeted significantly since he arrived at Anfield, now being valued at a measly £7m.

He has an average rating of just 6.5 on WhoScored for his Premier League performances during his stint at Liverpool, which is significantly less than the average score of 6.9 he received while at Arsenal.

Injuries have taken their toll on the Englishman following his move to the northwest, with the 29-year-old missing a total of 85 matches due to an injury, and having eight separate spells on the treatment table.

It might not have seemed it at the time, with Wenger reluctant to let the player go, but in hindsight, it has proved to be a brilliant piece of business and one of the few parting gifts the Frenchman gave to the club he managed for 22 years.
