Southampton manager Ralph Hasenhuttl, speaking to BBC Sport: "We made finishing drills in the final session yesterday and I think it helped [Adams]. It's what you are here for as a substitute that you come on and show your qualities. He played well last year as well.
"Both strikers did a good job. Nathan Tella was the man of the match today because he was hard to defend against and always hungry for every second ball."
Sheffield United manager Chris Wilder, speaking to BBC Sport: "We didn't deserve anything from the game. They [Southampton] were better. It was a great opportunity but it's been a tough week, playing Liverpool on Sunday and then down to 10 men after 60 minutes in midweek.
"We didn't show the quality we needed to hurt them. There was nothing in the game and then it was one great ball.
"It's a brilliant finish for Che [Adams]. I'm delighted for him and I've just spoken to him. He was here as a kid and was a bit of a loose cannon then, but he has got himself forward and he is a proper centre-forward."
