Arsene Wenger admits that at one stage during Tomas Rosicky's rehabilitation he feared the Arsenal midfielder's career was over.
Hamstring and knee injuries sidelined Rosicky for 18 months with his appearance in Saturday's pre-season friendly against Barnet his first since January 2008.
Wenger is confident the Czech international will still be the same player and hopes he could be available for the Premier League opener against Everton on August 15.
"There was a time when I was worried Tomas wouldn't play football again and he felt the same," said Wenger.
"But he had always led a healthy and dedicated life. Mentally he's also very strong. Of course you have to ask and hope if he will ever get back to where we want him to be and the answer looks like yes.
"We have to manage him well and prepare him well. If we comes through pre-season well he could start the season."
