Moyes wants to win the Community Shield in tribute to the work his predecessor did in winning the Premier League last season.
"Of course I will be trying to make the Community Shield the first trophy of many but if we win it's something that will have been earned by Sir Alex," he said.
"It is because of his good work in the Premier League last season that we're in the Community Shield.
"I'll do my best to finish off the job, but it's Sir Alex who will deserve a lot of the credit if we're successful at Wembley."
