Ollie Norwood praised United's 'togetherness' following Tuesday's victory over Brentford at Bramall Lane.
The skipper on the night had already fired in the opener from the penalty spot when Gary Madine was sent off in the first-half, but the Blades defended heroically at times and added a decisive second through David McGoldrick to secure an eighth consecutive home league maximum.
And Norwood heaped the praise on his colleagues, he remarked: "We stuck at it and gave ourselves a good start again.
"We got the first goal and when we went down to ten men, we had something to cling on to.
"We saw on Saturday, when Rotherham had a man sent off, how much they frustrated us and how difficult it can be to play against ten-men."
The influential midfielder added: "We've done it plenty of times on the training ground, overloading areas and we're very good at working hard and keeping our shape. There aren't many goals conceded because our defenders defend."
"You fear the worst really, if there is one team you don't want to face with ten men then it'd probably be Brentford, they move the ball well and have some good technical players.
"But we were resolute, there is a big prize on offer for us and we aren't just going to let it slip away. We showed we are a team and we have a real togetherness."
