We welcome Birmingham City to The Bolt New Lawn on Saturday for our first FA Cup third round appearance in 14 years.
It's our first ever competitive meeting with Blues, who currently sit 17th in the Championship table. Here's everything you need to know about Saturday's opponents.
Eustace signed a three-year contract as Blues boss last summer, replacing previous manager Lee Bowyer. Eustace was heavily linked with the Watford managerial vacancy in the summer, which was eventually filled by Rob Edwards.
Former Coventry City, Watford and Derby County midfielder Eustace's only previous permanent managerial gig was at Kidderminster Harriers, however he has coaching experience at QPR and the Republic of Ireland national team.
Despite a recent blip in results, Eustace's Blues remain only seven points off the play-offs - such is the tightness of the Championship. He has given opportunities to young players, with teenagers George Hall, Jordan James and Jobe Bellingham all receiving game time under his management.
It's difficult to know exactly what sort of team Birmingham will field for this FA Cup clash - but Arsenal loanee Trusty has been a stellar performer for Blues this season.
He has played every minute of Birmingham's Championship campaign so far (and therefore may receive a rest) and is thoroughly enjoying life in the Second City.
The towering defender has bagged three goals from the back and has got Blues fans singing “USA! USA! USA!”
Interesting fact: Trusty's sister is a vegan chef.
