Cavan Sullivan has signed the largest homegrown contract in MLS history with the Philadelphia Union. Sullivan, 14, will transfer to Manchester City after he turns 18 as part of the deal.

Sullivan's older brother, Quinn, 20, has been a first-team player on Philadelphia since 2021.

"I've always wanted to start my career here because this is my home and I've always been on the sidelines of Quinn's games and I've been in and around the facility when my uncle worked here," Sullivan told ESPN. "So, I've always been inspired and to play in front of this culture, and these fans are special.

"But I also think the collaboration between the Union and the City Group was -- I think that did it for me. I always watch Man City. They're like every kid's dream team. For [Philadelphia and Man City] to come together and agree on something -- I sat with my family and my agents and we decided that it was the best plan."

On whether Sullivan will debut before July 29, Union coach Jim Curtin told ESPN: "If he's healthy, he'll do it."

Sullivan's best position is still yet to be determined, but he's an attacker who is dynamic with the ball at his feet and confident taking on defenders. Curtin said he could serve as a second striker or an attacking player and that his versatility will be an asset for the Union.

"I would say the big word is 'playmaker,'" Sullivan said. "That's what I try and be every game, every training. I think I'm good on the dribble. My decision-making is pretty good, and my vision on the field is one of my qualities."
