Peyton Manning: 'I Think Von Miller Will Re-Sign' ... 'Both Sides Want It'

Peyton Manning is weighing in on the standoff in Denver ... telling TMZ Sports he believes Von Miller WILL re-sign with the team ... "I do not see that being a problem at all."

The former Broncos QB touched down at LaGuardia Airport -- and was very optimistic that both sides will be able to come to the table and get a deal done before the season starts.

The backstory ... just last month, Von shot down the team's 6-year $114 million offer (with $40 mil guaranteed in the first 2 years). Miller reportedly wants more than $60 mil guaranteed in the first 3 years.

"I know both sides want to work it out," Manning told us.
