De Gea is returning to his best form as United sit top of the table.
He told United Review: “I'm trying to lead and be a leader.
"The young lads might look at me and see I have been here a long time, and played a lot of games, and I think the most important thing is to show your experience on the pitch and in the games by trying to help the team.
“I try to make big saves in the games and train hard as well. Training is very important too and always to give your all.
"I have the experience of winning big titles here. I know the feeling of winning things and, this year, we have an opportunity to win a trophy and we cannot miss big chances."
