Liam Moore is looking forward to the test of Watford at Madejski Stadium on Wednesday night, with the Royals hoping to build on two straight away draws in the league.
The Hornets, meanwhile, have made a flying start to the Premier League season - winning all three matches they have played in the top tier so far this term.
Javi Gracia's side overcame Crystal Palace on Sunday with a deserved 2-1 win at Vicarage Road, with Roberto Pereyra and Jose Holebas firing Watford to the win against a well-fancied Palace side.
"It'll be a tough test again, but it's a cup we want to progress in," Moore explained. "We've got a big squad, so it's a good opportunity for the lads who haven't been getting many minutes to play.
"It's a good oppotunity to progress and show what we can do against a Premier League team.
"There's lots of competition. You look at the players on the bench and even some that didn't make the squad [at the weekend], it's a really difficult job for the manager.
"All we can do as players is train hard, then when we get the opportunity, show what we can do!"
