Lee Johnson praised three of his new signings as Sunderland beat Wigan to reach the fourth round of the Carabao Cup.
Debutant Leon Dajaku, Dennis Cirkin, and Niall Huggins, all impressed as the Black Cats beat the Latics 2-1 at the DW Stadium thanks to goals from Nathan Broadhead and Luke O'Nien.
"I thought he was excellent," Johnson said of on-loan Union Berlin winger Dajaku.
"You can see the way he brings others into play, with that football intelligence.
"He worked hard for us and was bright.
"He could have scored a couple. I've seen him strike those ones in the second half inside the post and he maybe could have been a bit more selfish there. In the first half it's a great touch to put him one-vs-one, and unfortunately he's just made the wrong decision.
"He's had to work really hard the last few weeks and it's really nice that he's been able to make a good first impression."
And of Cirkin and Huggins he added: "Dennis is going to be a top player.
That's an unbelievable signing.
"And I thought Niall Huggins was outstanding, as well. You just wouldn't want to mark them, would you? They're like Duracell bunnies.
"We've seen that in training and it's almost embarrassing that you can't get them on the pitch at times.
"I wish we could bring back give subs because you feel almost uncomfortable not being able to get them on the pitch when they're doing so well."
But Sunderland's man of the match was Alex Pritchard, who provided the assist for the first goal and was excellent throughout.
Johnson said: "“He's got up to that fitness level now, hasn't he?
"You couldn't get the ball off him in a phone box, could you?
"He's so good with his feet, and you can't underestimate how much that drains the opponent because you think you've got him, but then all of a sudden he touches it away and you've either got to foul him, which buys us time, or he skips out of trouble and breaks the line and then next time you think, 'I’ve got to over-cover'.
"It's just having that intelligence on the pitch to be able to pick out a spare player, and that is what we have got very good at through a lot of hard work in training."
