Arsenal manager Mikel Arteta has admitted to experiencing deep personal doubts regarding his ability to deliver major silverware before securing the Premier League title this week.
The North London club ended their agonising 22-year drought on Tuesday night when title rivals Manchester City dropped crucial points away at Bournemouth.
Arsenal's historic triumph caps a remarkable journey for the Spanish tactician, who previously faced immense scrutiny during a turbulent period of rebuilding at the Emirates Stadium.
"Yes, we won the league," Arteta said in a press conference on Thursday via Sky Sports News. "But the most proud I've been is how we've won it.
"We showed very important values not only in sport, but in life. Perseverance, to be resilient, to be composed in moments when people are doubting. And to be vulnerable.
"I've asked that question to myself: am I good enough to lead these players to win a major trophy? Until you do it, you cannot validate yourself."

Arteta revealed that a unique team meeting centred around a tree at the training ground helped forge the necessary unity and mental resilience within the squad.
"One of the main ones was a meeting we had here, at the training ground next to the tree, when I got all the players together," said the Spaniard.
