Head Coach Leonid Slutsky knows his players will face a serious test of their character when they take on Fulham at Craven Cottage tonight (KO 7.45pm).
The Tigers are still licking their wounds after a 5-0 drubbing at Derby last Friday and will be looking to bounce back against the Cottagers, with Slutsky admitting the side owe their travelling fans a performance.
"This isn't just a match for us now, it is a big test for our character and for our willpower," said Slutsky.
"It is a key moment in this season and we must show a reaction after what happened at Derby and that unbelievable defeat.
"It is a serious pressure now because everybody understands that we must recover quickly from what happened. The pressure is for the players, for the staff and for the Head Coach after a difficult moment in building a new team.
"Maybe it is better that we have this midweek game because it means there isn't as much time to think about what happened at Derby, but it also means we haven't had as much time to change some things because really we want to change some very important things in the team.
"It is important that we give the travelling fans a good performance. We still apologise to those that went to Derby. We know that a Wednesday night is not the best time for fans to be travelling to a game in London, but we hope that the fans that do go to the game will be right behind the team as the support is very important to us."
Slutsky's men will come up against a Fulham side that has matched the Tigers' points tally for the season so far and the Russian is expecting a tough evening at a ground he knows well.
"I think they have changed their model a little bit since last season," added Slutsky.
"They have very fast players in attack and are very dangerous on the counter-attack. However, they don't just rely on this and the class of player they have means they are good at many different systems.
"For quality, I think Fulham were the best team in the Championship last season and they are a very dangerous side.
"I have been to Craven Cottage many times and I was there at the weekend to watch Fulham's match against Cardiff."
