Be in with the chance of being a mascot for one of this season's FA Cup semi-finals.
Junior supporters can enter our competition to walk out with a player at Wembley in April.
The FA are looking for representatives from various clubs to emerge from the tunnel with whichever teams make it through to the last four clashes.
The prize is available for any young fan aged between seven and eleven who is attending the Sheff Utd match.
To enter, an adult will need to fill out a competition entry form at the welcome desk in the family funzone on Saturday before the match.
The winner will then be chosen at random and notified next week.
You can enjoy the family funzone after you have submitted your entry.
Enjoy the build-up to the game by checking out a host of free activities in the Villa Park Indoor Academy from 12noon.
Activities include speed cage, gladiator duel, cactus hoopla, golf chip, darts, snowboard simulator, noughts and crosses and assault course.
Mascots Hercules and Bella will be coming along too!
To be eligible, children must be between seven-eleven years of age and attending the Sheffield United third round fixture. Once the semi-finalist teams are confirmed, The FA and Aston Villa will send you detail of everything you need to know about the day. We will send you a consent form to fill in and return before the specified date.
You will be provided with a player escort kit (shirt, shorts, socks) on the day, a goody bag and a matchday programme.
You will receive two tickets to the game - one for the parent/guardian and one for the child.
The team you walk out with on the day will be allocated by The FA. However, if Aston Villa makes it The FA will do their best to make sure you walk out on to the pitch alongside them.
