The Chiefs can equal the record of their AFC West rivals, the Denver Broncos, with a win to put pressure on John Fox's side going into the final two weeks of the campaign, but he is not taking the Raiders lightly.
Reid told reporters: "I know their head coach [Dennis Allen] is one of the great defensive minds in the league, and the things that they do, I think, they're doing very well.
"The way they're executing the defense has been better than the first time we played them and we punted the first five times we had the ball. I got it, I think they're very good and we're preparing for a good defense."
The Chiefs currently hold the number five seed in the AFC playoff race with a 10-3 record.
