#7 Mikel Arteta
Arriving at Arsenal in 2011 after a great time at Everton, after the club let go of Nasri and Fabregas, few expected Arteta to become the leading light but the Spaniard did exactly what the few expected.
Cementing his place in the team, the midfielder went on to gain a legendary status by ending Arsenal's trophy drought and winning two FA Cups as he captained the side in two finals.
His career in coaching opened in 2016 when Manchester City appointed him as an assistant coach under Pep Guardiola and the experience he gained there went on in becoming a crucial fact of consideration when the Arsenal job opened up after Arsene Wenger left.
The job, however, fell to Unai Emery but Arteta is not going unnoticed. If he ever becomes a manager, he's going to combine the best of two worlds, the worlds of Guardiola and Wenger just like Thierry Henry is planning.
Arteta doesn't stand out in glory as the other legendary players mentioned above but he's a legend in his own way and amongst all the upcoming managers, he's one of the most interesting ones to have an eye on.
