Nottingham Forest manager Martin O'Neill is expecting a tight contest when The Reds travel to Birmingham City on Saturday.
Garry Monk's men are renowned for their battling qualities and O'Neill is in no doubt about the difficult of the task that awaits his side as they get set to make the journey to St Andrew's this weekend.
Speaking to iFollow Forest he said: "It will be a really tough game. I've watched the Championship from a distance for some considerable time and I think they've done exceptionally well.
"They fought back at Swansea on Tuesday night with only ten men and they have shown tremendous grit and determination throughout the season so it will be a difficult task for us, as it always is at Birmingham.
"We certainly wanted to add to the squad so we can compete to reach the play-off places and I just want to have a real go at it. Of course we have a little bit of ground to make up and every defeat just knocks you back a bit and we're reaching a stage where every result is extremely important."
O'Neill recruited four players in the final days of the January transfer window but is not concerned about where those new faces will fit into his side.
He said: "I am extremely open-minded about the formation we'll play, in fact, it is far from fixed in my mind. We went with two up front in my first game against Bristol City and it didn't work so we reverted to 4-3-3 against Wigan and I thought we did fine.
"I'm hoping that over the course of the rest of the season, we will develop a couple of ways of playing so that when the players get used to it in training, they will be able to utilise different formations throughout a particular game.
"We've worked hard to strengthen the spine of our side during the transfer window. January is a very difficult time to bring players into the football club but we feel like we have recruited the necessary number of players into the squad."
