Speaking at his pre-match press conference ahead of Sunday afternoon's match, Howe was full of admiration for United.
He said: "It will be a very, very difficult game for us this weekend. I think they've done an outstanding job this season.
"Chris Wilder, the staff, the players - incredible job. To get promoted is hard enough, and then to stabilise yourself in the Premier League is incredibly difficult as we found...but they've been superb this season.
He added: “Their style of football, the way they play, their collective attitude...it's been excellent to see from the outside."
