Swansea City have made the trip to the Midlands for a fourth round FA Cup tie that sees them take on Birmingham City, who knocked them out of the Capital One Cup earlier this season.
The Blues beat the Capital One Cup holders in the third round of this year's tournament, when goals from Dan Burn, Matt Green and Tom Adeyemi earned them a 3-1 win. And manager Michael Laudrup says his side can expect "competitive" opposition once again.
Pablo Hernandez and Jonathan de Guzman are set to return from injury for Swansea at St Andrew's.
Winger Hernandez has been sidelined for over three weeks with a hamstring injury, while De Guzman has been hindered by a calf problem, but both are in contention to face the Blues.
But Nathan Dyer, Michel Vorm, Michu, Jose Canas and Garry Monk all remain out of action for Swansea, who knocked out Manchester United in the last round earlier this month.
Given their league situation, Swansea could be forgiven for viewing their Birmingham Cup tie as a distraction.
But Laudrup said: "In every game, I will try to have a competitive team whether I make two, five or seven changes.
"In most of the games in my time here no-one has been able to say we could not do enough against the opponent and the team tomorrow will also be competitive and hopefully move on in the competition.
"If you win, it always gives us something to take on to the next game. I hope that will be the case as we all know Tuesday against Fulham is a key game in the league."
You can watch full highlights of the match on ITV at 10.45pm this evening.
