The midfielder didn't give Vieira a second on the ball and the Arsenal captain was clearly ruffled as we went into a 1-0 lead in the first half.
Unfortunately, as we all know, Arsenal levelled in first half injury time before taking a grip on the game by capitalising on our mistakes to lead 3-1 and then keep their heads in front as the final score ended an amazing 5-4.
You could tell Brownie was desperate to concentrate on the positives afterwards but struggled to.
"It's been a great week for me personally, back in the centre of midfield, playing against Burnley and now the derby," said Michael.
"I enjoyed the battle and playing in the middle of the park and it was a great atmosphere to be in.
"But we've lost the game and it's disappointing.
"We gave four goals away really. The boss has pointed that out but we have to look on the positive side, we've scored goals and we have to pick up and start again.
"Having said that results are what we need and we would rather have played poorly and got the result to be honest.
"We have to look at the positives though, that's the right thing to do and we can look at the first half especially and the fact we've scored four goals against Arsenal. Unfortunately, we've lost the game."
Michael Brown relished his battle against Patrick Vieira on Saturday but couldn't hide an overwhelming sense of disappointment afterwards.
