The 20-year-old only made six appearances in Emery’s debut season at the club, but he has almost registered double that amount just two months into his second.
Willock has become a key member of the Gunners squad this term; featuring seven times in the Premier League, starting on three occasions, while getting the nod and scoring in each of their two Europa League outings.
The midfielder also found the back of the net in a 5-0 Carabao Cup victory at home Nottingham Forest.
But Willock has revealed that he was anxious when Emery first arrived at the club, admitting he was initially too eager to impress the Spaniard.
“I always work hard in pre-season and try to push myself to the limits. When I get back, I’m ready to compete with everyone,” he told The Sun.
“But this pre-season was about my mental state. I had to work on myself and think about strategies.
“When the new manager came in, I wouldn’t say I was fearful but I was a bit apprehensive because it was unknown waters.
“I wanted to impress him so much. It didn’t really go that well in his first pre-season. I just wanted to impress him and I was a bit anxious to do it. Not many things went well for me.
“I wanted to think about how I was going to impress him and how I was going to push on to the next level. That’s what I did.
“I took time to think about it, worked hard, got my head down and when I got back, it worked.”
Willock is starting again for Arsenal in their Premier League clash with Sheffield United tonight.
Emery has dropped Dani Ceballos in order to start Willock at Bramall Lane, while Alexandre Lacazette is back on the bench after returning from an ankle injury.
