Standing in Palace’s way are the competition’s most successful side. Manchester United have lifted the FA Youth Cup 11 times, with a rich history that includes the famed “Busby Babes” and the Class of ’92.
Alonso is fully aware of the test ahead, but insists the focus must remain on his own side.
“Manchester United are one of the best teams in the country,” he said. “They have very good players and they are a strong team.
“Of course, we analyse them and we respect them – but we have to focus on ourselves, play as a team and give everything. We don’t need to put too much pressure on ourselves.”
For Alonso, handling the occasion will be just as important as the football itself.
“For me, the key is to control our emotions,” he added. “We have to stay calm, follow the game plan and not try to do anything different.
“When you play in a big stadium, in a big game, this is the most important thing. If we do that, we will be fine.”
