Sheffield United boss Chris Wilder: "The timing and manner of the goals really all afternoon hurt us.
"I really fancied us and we did as a football club. We got paid a compliment with the way they set up and you could see, led by the manager, that they thought this was going to be a tough afternoon.
"Apart from the last 10 minutes, it wasn't a foregone conclusion. The goals really, at any level... after Tuesday night, the first thing we needed was to have a bright start and get a foothold in the game and we didn't."
Tottenham boss Jose Mourinho: "The performance was good. The team was very dominant, created enough chances to kill game in the first half.
"In the second half, the intention was the same. A very basic mistake gave them the goal with the only chance they had, but then we had a genius action to bring us again to a two-goal advantage."
