Arsene Wenger thinks the last four months have been crucial to Aaron Ramsey's return to top form.
The Welsh midfielder has scored six goals in as many games and has received widespread praise for his all-round performances at the start of this campaign.
"He has a great engine, great spirit and has an obsession - he wants always to be better"
Wenger highlighted the final "three or four" months of last season as a vital period in Ramsey's resurgence and thinks he is completely over the horrific injury he suffered against Sunday's opponents Stoke City in February 2010.
"It took him a long time to get completely over that, especially in the duels, in the fights. He had a little resistance to go into the fights for a long time," said Wenger.
"It was in the last three or four months of last season when he started to come back.He had a difficult period in mid-season where people became a little bit impatient with him.
"I always thought he would score goals if he improved his technical quality. When you watched the games, you saw him always in good positions in the box."
The Frenchman hailed the 22-year-old's mental strength after he endured criticism after his return from that long-term injury.
"I believe that every test that you pass, you come back mentally stronger," said Wenger. "It's a good test as well because in our career you go through periods where people like you a bit less or hate you a bit more and if you can deal with that it makes you stronger.
"He has a great engine, great spirit and has an obsession - he wants always to be better."
