Ollie Norwood described Tuesday success over Brentford at Griffin Park as a 'huge win'.
Speaking in the aftermath of United's victory in the capital, the stand-in skipper, who notched a goal of the season contender, praised the character of the squad.
He remarked: "It was a huge win for us, a huge marker to put down.
"We keep talking about last Saturday and we won't forget about that as a group of players because we know it wasn't good enough and we let the fans down at Rotherham."
Norwood added: "We've held our hands up and admitted we made mistakes, but it's about the reaction in football and the game couldn't come round quick enough for us.
"We had the bit between our teeth and we've taken the first step to put things right.
"The Gaffer told us in no uncertain that level of performance won't happen again, there were some choice words after the game at Rotherham, but it's the best dressing room I've been in as a player and we tell each other.
"We stick together and you can how much it means to everyone when Leon comes on and scores the winner."
