The clubs were fined a combined £355,000 after two players were sent-off, 10 were booked and two mass confrontations took place in Villa’s 2-1 win at the GTech Stadium in December, 2023.
Watkins sparked the first melee when he scored the away team’s 85th minute winner and then pointed at a home supporter he later claimed had been abusing him throughout the match.
The 29-year-old, who joined Villa from the Bees for £33million in 2021, has regularly been a thorn in his former club’s side, scoring four goals in his last three appearances against them.
And boss Emery is confident he can block out any noise as he tries to fire Villa toward a vital win in the race for European football.
Emery said: "I think you have to be intelligent and Ollie is an intelligent man. We are going to face the match competing and knowing the supporters of Brentford, they are going to try to support their team.
“Maybe we had to accept some words aimed at us, but we are professional, we are playing at a high level.
“We were playing in Bruges on Tuesday, the supporters of them were supporting their team and saying things against us!
“It's normal in football. Of course, respect is very important, but in my career as a coach, I always accept to play with our supporters, to play with the opponent's supporters using sometimes words that are not really respectful to us, but not really taking moments like that as something personal.
"I think it's because they are supporting their team, they are supporting their players, they are supporting their coaches and we had to accept it.”
Brentford’s Ben Mee and Villa’s Boubacar Kamara were sent-off in a match considered one of the dirtiest in Premier League history.
Emery and Thomas Frank were both booked in a tempestuous climax but on Friday the Villa boss was effusive in his praise for the Dane.
The Bees, who have not won any of their last six home Premier League matches, sit one spot behind 10th-placed Villa in the table.
Emery said: “The coach, I think he is very intelligent and I think he is very ambitious as well in how he is trying to get a new way for them, playing in different tactical structures and ideas but always growing up and being better.
“Of course, two years ago when we first got into Europe, we were competing with them.
“If we lost against Brighton in the last match when we got Conference League, they were in.
“More or less in two years, I was seeing them as an opponent for Europe to be in the top ten and it is still the same. They are with us.”
Ross Barkley remains sidelined but Emery revealed fellow midfielder Amadou Onana is “close” to making a return from injury.
