WBC, IBF welterweight champion Errol Spence is not only motivated to win his upcoming defense, but he also wants to become the man to retire Manny Pacquiao.

Pacquiao, 42-year-old, will challenge Spence on August 21 at the T-Mobile Arena in Las Vegas. The event will be carried by Fox Sports Pay-Per-View.

The eight division world champion has been inactive since July of 2019, when he won a twelve round split decision over Keith Thurman to capture the WBA title. He was later made a "champion in recess" due to inactivity.

Spence, who is younger, bigger and highly skilled, is the big favorite to win by the oddsmakers.

He gives Pacquiao a lot of respect because he could have selected a much easier opponent at the weight class.

"I want to retire him but I do respect him for taking this fight and being a real fighter. He could've picked Joe Blow or somebody, or an MMA fighter just to get a huge paycheck. Instead, he took the biggest challenge in the division," Spence stated to Morning Kombat.

At the moment, Spence views his knockout win over Kell Brook as the biggest moment of his career. He traveled to the UK to score a stoppage of Brook to capture the IBF title in 2017.

"I feel like the Kell Brook fight was [more important]. If I didn't win that, I would still be here. but it would've been a harder road. It solidified me and was my first world title fight. To go to his country and stop him for the title, at that time he was arguably the best welterweight in the division. I feel that was the biggest fight of my career," Spence said.
