Blades skipper Morgan said: "I think Middlesbrough will be disappointed not to have done as well as Newcastle and WBA, but then again we're not totally satisfied with our current position.
"They have had a change of manager and will no doubt be upset with how things are going at present, but they've got plenty of quality players and we must respect that.
"They let a good manager go in Gareth Southgate, but replaced him with another good boss in Gordon Strachan, so I suppose it just hasn't happened for them and I don't think they'll be relishing a trip to Bramall Lane."
