It's not quite the same father-son story that fans love to see at the highest level of the sport, but
He's of Bulgarian Descent
Vassilev is emerging as the latest American wonderkid who could break into the United States Men's National Team, but the teenager could have also chosen to represent Bulgaria.
His parents both settled in the United States in the late 1990s, with
Scouted at the Under-17 World Cup
Despite making a name for himself at youth level in America, it wasn't until the Under-17 World Cup in 2017 that Vassilev started to attract attention from European clubs.
The United States, who were managed by John Hackworth, scored 11 goals on their way to the quarter-finals where they were knocked out by eventual champions England.
Vassilev joined Aston Villa the following year.
Vassilev's made a name for himself recently as a goalscoring threat in the final third, but the 18-year-old has actually featured in almost every position imaginable.

Wonderkids for Teammates
Vassilev came up against all sorts of household names at the Under-17 World Cup - the England side alone had Phil Foden, Jadon Sancho and Rhian Brewster, who scored a hat-trick in the quarter-final to knock the United States out.
But throughout his rise with the national team, Vassilev's also been on the same side as some young players who are starting to attract attention from Europe's biggest clubs.
At the Under-17 World Cup alone, Vassilev played alongside
He's Outscoring the Big Six's Stars
The Premier League's Under-23 division gives fans a chance to catch a glance at their side's biggest youth prospects, and this season has been no different.
West Ham's Nathan Holland earned himself a loan move to Oxford United after scoring 12 goals in 13 games, while Curtis Jones is firmly part of
For Vassilev, his six goals has him level as Aston Villa's joint-top goalscorer at Under-23 level.
What's even more impressive is that the 18-year-old has already scored more than some of the brightest prospects at the Premier League's biggest clubs, like Tahith Chong, Tyreece John-Jules, Rhian Brewster and Charlie Brown.
