Joyce was asked about one player in particular, substitute Tom Lawrence who played a key role in turning the Tottenham tie on its head.
"Tom's not had a lot of football and as I said to him before the game, he can't sustain 90 minutes," said Joyce. "If we'd had a game plan and looking for him to make an impact, I just thought it was better that way round [Lawrence being sub] than him starting the game and having to come off, gambling on us scoring early. He's got to have an operation maybe tomorrow or Wednesday so we had that on our minds as well."
Turning to Tottenham, the winners of two group stages this term, Joyce said: "I think Tottenham have proved this season that they are an excellent passing side.
"They can handle the ball, they've got a lot of creative players and I think they've got several players that will make the grade in that team. They're a bit older than us. They're a bit more experienced. But I just thought the general fitness of our boys told in the end."
Joyce was naturally thrilled his Under-21 players could follow in the first team's footsteps and win their league, to ensure a period of celebration and reflection ended on one more high note.
"Officially this is the gaffer's [Sir Alex Ferguson's] last game at Old Trafford. It's been an emotional weekend for everyone at the football club, it was another emotional day yesterday and we're delighted to have finished the way we have tonight."
