Jamal Blackman says the Blades mustn't panic, despite suffering consecutive away losses at Middlesbrough and Cardiff City.
Having gone done to a harsh defeat on Teesside at the weekend, a goal in each half condemned United another loss in Cardiff on Tuesday, but the on-loan goalkeeper didn't feel there was too much between the sides.
He remarked: "It was a game that saw both sides have opportunities. Cardiff were clinical and we didn't take our chances. It was one of those games that could have had a very different outcome had we scored first.
"We left Wales frustrated and disappointed, but always with a few positives from another decent performance."
Blackman added: "Cardiff are a big, physical and pacey team, they have threats all across the field and from set-pieces with their size they were always going to be a threat aerially.
"Unfortunately we perhaps didn't handle them as well as we could have done, but we're still working hard and we will continue to improve.
