We travel to Birmingham to take on a Villa side struggling at the foot of the Premier League.
But Toby says our group of players will take nothing for granted at Villa Park - not least as we lick our collective wounds after losing 3-0 against Borussia Dortmund in the Europa League on Thursday night.
"Everyone is disappointed after Dortmund and it will take a couple of days, but then the focus is on Sunday," said the defender who came in for a busy night alongside Kevin Wimmer at Signal Iduna Park.

"It’s good to have a game so quickly. Everyone will expect us to win but this will be a difficult game and we have to be tough to beat them.
"We will need to concentrate and play at a high level otherwise it will be difficult. We have to be focused and as I said, we have to be at the top of our game because if we lack a little, it will end up being a very difficult game for us."
Meanwhile, like his team-mates, Toby left Dortmund with regrets after the 3-0 reverse against the Bundesliga title contenders in the Round of 16, first leg.
"We started okay but they then took control of the game and it was difficult for us," reasoned Toby after Dortmund rained in 20 efforts at goal to our three.
"If you have a tough night like this you still want a result where you can change it at home but now it’s very difficult, 3-0 is tough to get back now. We have to focus on Sunday first and then we’ll see about the second leg."
