Denver Broncos quarterback Peyton Manning believes that teams across the NFL will have a hard time stopping tight end Julius Thomas this season.

Thomas scored two touchdowns and had 111 receiving yards in his side's 49-27 win over the Baltimore Ravens in their opening game of the campaign.

"I am not sure how they will answer it, or if they will, but it will be interesting to see how teams play Julius all season," Manning told the club's official website.

"He is a big guy, he definitely will make teams have a conversation, and that is what you want."

Manning tied the NFL record for the number of passing touchdowns in one game with seven against the Ravens on Thursday.
