With Fulham having canceled out United's 2-0 lead in the final minutes, Sesko struck in injury-time to earn the 3-2 win.
Carrick said afterwards: “Huge moment. I’m so, so pleased. Everyone in the changing room, players, staff, delighted for him, absolutely delighted for him and the reception he got when he came back in the changing room told us everything. Confidence, it wasn’t so much that.
"He’s been fantastic, we’ve worked with him a lot in different ways over the last couple of weeks. He’s bright in training, he’s looked dangerous, he’s done extra. The coaches have done a lot of bits on the side and Travis (Binnion), particularly, has done a lot of work one-on-one with him.
"Ben’s a big talent, he’s got so many positive things. And today’s a huge goal because that feeling as a striker to score a winner in front of the Stretford End late like that, it’s what you dream of. After missing the chance, which is what it is, strikers miss chances, to go again and put that away. Absolutely so, so pleased for him. He really deserved it.”
On Kobbie Mainoo's performance on the day, Carrick was equally as pleased.
He also stated: “Yeah, I think Kobbie’s performance was very, very good today in so many ways again. You could see the way Fulham played and overloaded the middle at times and the movements, there was a lot of work for Kobbie and Case to do, in particular in the middle of the pitch.
"So that was without the ball, I thought he’s done terrific in that. And then with the ball, I’ve spoke about it before, about the ability to just cope, he’s not really fazed by it. He plays his game and he understands what’s needed, it’s the moments of quality.
"It’s what we come to expect from him in many ways and what I come to expect, but you forget how young he is still. He’s still got loads to come, but seeing him today and playing with that kind of confidence and a belief is a real joy to watch to be honest, for any young player.”
