What has Emery said about the tie?
“It’s a way for a trophy and it’s a way for Europe. The winner is playing next year in the Europa League.
“We have three ways [to get into Europe]: Premier League, Champions League and FA Cup. We are not contenders in FA Cup to win this trophy.
“To try to compete in this competition and to have a way for a trophy is very important. And then prestige. Every player, the club, the coaches – everybody would like one way trying to get prestige as well.”
“We are being consistent in this competition this year. At home against West Ham and Tottenham we played a great two matches and we won.
“Tomorrow is another opportunity to keep being consistent. Our demands are in different ways, individually and collectively, to get confidence, get comfortable, try to transmit to our supporters our wishes in this competition.
“We are not contenders, but in case we can continue in this competition we are going to be closer to competing for something important.”
Tech trial
Villa will be part of the first use of semi-automated offside technology (SAOT) after the Professional Game Match Officials Board (PGMOL) confirmed the plan to introduce it in the FA Cup this week.
Emery's side will be the first team to experience SAOT at Villa Park.
Villa defeated Tottenham 2-1 in their previous FA Cup game to book a place in the fifth round for the first time in 10 years.
In the seven ties where Premier League teams have been drawn at home, SAOT will be used for the first time with just Preston North End and Burnley the only tie not using the new technology.
Selhurst Park, the Etihad Stadium, St James' Park, Old Trafford and the Vitality Stadium will also use the technology.
It will help to provide more efficient placement of the virtual offside line as it will be based on player tracking.
Virtual graphics will be implemented to enhance both the in-stadium and broadcast experience for fans.
It's essential to note that while this technology will improve the speed, efficiency, and consistency of the process, it will not affect the accuracy of decision-making.
To achieve this, the Premier League has partnered with PGMOL and sports data and technology company Genius Sports.
Together, they have developed a new SAOT system, which will be used for the first time in a live competition.
