Ciaran Clark reserved special praise for Newcastle United teammate Martin Dubravka after Thursday's 2-0 win over Sheffield United.
The Slovakian produced a number of fine saves to deny Chris Wilder's side.
Speaking after the game, Clark said: "This is a great feeling. We knew it would be a tough game coming here, they are on a good run of form and their league position shows that.
"We stayed concentrated for most of the game. They had a couple of chances in the first half but Martin Dubravka made some great saves."
