The big defender was naturally distraught that a cruel deflection cost us the points for a second successive away game at Blackburn on Saturday and is happy to swiftly return to action.
A place in the quarter-finals of the Carling Cup looms for the victors and Dean is determined that there will be no further gloom when the final whistle sounds.
"It is a chance to put things right!" he rallied. "It is a cup game and there will be a different atmosphere and that sometimes gets you play with more freedom.
Dean acknowledges that the team rode their luck in mounting a rearguard action against a rampant City in the away fixture at the end of September. City have since suffered a bit of a wobble and have lost their last three in the Premiership
"We did ride our luck. There is no disguising that they were the better team and created some very good chances.
"But they've been a bit indifferent lately as well and their confidence might be a bit lower than it was then. We've got to take advantage of that."
Dean feels that this is another example of the topsy-turvy form seemingly being suffered by every team outside of the top three at present. It appears that none of these sides can string a significant number of positive results together.
"This season is unbelievable when you look at the league," he added. "That is why it is more disappointing for us after Saturday - if you put a couple of wins together you find yourselves up the table.
"Everybody is beating everybody and it is just a strange league this season.
"I think it is good on the whole. It is good that a team like Fulham can go and get a point at Arsenal and, another week, get beaten by a lower team.
"It is a good competitive league this season, outside of the top three each team seems to be capable of beating every other."
Dean Richards describes the Carling Cup clash against Manchester City on Wednesday as 'a chance to put things right'.
