Burton Albion boss Gary Rowett saluted substitutes Billy Kee and Marcus Harness after his side came from behind to maintain their 100 per cent start to the season with a 2-1 win over Dagenham and Redbridge.
Kee scored twice in four minutes late in the game to clinch the victory after Jamie Cureton had given the Daggers, who remain without a point, a deserved first-half lead.
Rowett said: "There's probably no-one better to have in your squad to bring on than Billy
"He showed character to take the penalty and then took the winning goal really nicely.
"And Marcus had a big part to play in both of the goals, which is a glimpse of what he has to offer. I think he's a real talent for the future."
Rowett was relieved that Burton stuck to their task after the Daggers had controlled the first half.
The Burton boss added: "I think that sort of result is what good teams are made of because good teams have to find different ways to win games.
"If you've got any ambition you know you've got to be prepared for all eventualities. That's why we changed it because the way we were set up in the first half just didn't work.
"You need to be flexible and have players who can come on and win games, but you also need the resilience and character we showed today.
"Sometimes games become a little bit of a fight and a little bit of scrap and you have to find ways to deal with it."
Cureton punished a napping Burton defence by nipping onto an Ashley Hemmings header and steering a low shot past Jon McLaughlin in the 18th minute.
Kee made the most of his opportunity to open his account for the new campaign when he drilled home from the spot in the 84th minute after Harness had been tripped in the area by Luke Howell.
Kee then turned on a Harness cross to fire the winner into the bottom corner.
Daggers boss Wayne Burnett said: "We have to be better than we were in the second half.
"I don't think their first goal was a penalty because we won the ball quite cleanly, but the second was an absolute joke defensively from our point of view.
"We allowed a player to have a touch, turn in the box and shoot at our goal - and if you allow that to happen then you concede.
"That was not good enough and we have to be better than that because our fans have travelled a long way and have gone home very disappointed.
"We felt we weren't in any danger in the first half, quite comfortable in fact.
"But the second half performance showed we need to be braver and better with the ball.
"You can play well but if you don't defend well results like this happen."
