The defender played a big part this season after initially struggling and says it could be one of his best ever.
The Spain defender enjoyed a fine season with the Gunners as he made the left-back spot his own, playing twice as many minutes as he managed in his first campaign with the club.
One of the games he started was the FA Cup win over Manchester United, in which he managed to bag a rare goal in a strong display from Arsene Wenger’s side.
“One of my favourite moments was scoring against Manchester United,” he told Arsenal Player.
“I remember the game because I scored a goal, we won at a really difficult ground so it was the best [individual] moment that I had.”
After a short spell at centre-back earlier in the campaign, Monreal returned to the left-back berth to play a key part as his side went 10 games unbeaten between March and May, becoming one of the in-form teams in Europe.
Aside from his performance against United, the defender also played a key part in the FA Cup final against Aston Villa as he was heavily involved in Theo Walcott’s opening goal.
And the defender believes that this season may have been amongst the best of his career so far, after seeming to settle at the Emirates and thriving when given the chance in the side by manager Wenger.
“Before I played for Arsenal, I played for two different clubs, seven seasons in total, and at a good level,” he added.
“This season has probably been one of my best, maybe not the best but one of the best. I’m very happy about that and I would like to continue it and keep going next season.”
