Christian Pulisic can be grateful football is played on land rather than out at sea as he proved just how difficult it is to do kick-ups on a boat.
The 22-year-old is making the most of his time off before he returns to London for a first pre-season under Chelsea boss Thomas Tuchel.
Pulisic took to Instagram to share what he had been doing with his time, which seemingly involves a mixture of fishing and football.
He initially looked confident as he juggled the ball with his right foot, but went for one trick too many in what proved to be a costly error.
At the start of the video, someone in the boat says: 'Got a Goliath Grouper that Christian caught, and he's teaching it how to play soccer.'
The fish was unlikely to be impressed with the lesson though, as Pulisic lost control of the ball and slipped out of the boat and into the sea, landing on top of the fish.
The Chelsea star was pulled back into the boat, nervously laughing after his showboating backfired.
Pulisic certainly picked the wrong fish to land on and annoy - the Goliath Grouper can reach lengths of up to 8 feet while weighing up to 320kg.
Last season, Pulisic became the first American to play in a Champions League final after Chelsea triumphed over Pep Guardiola's side.
He added more silverware to his cabinet last month, scoring the 114th-minuter winner as the United States beat Mexico 3-2 in the final of the CONCACAF Nations League.
The winger will be hoping to put his injury problems behind him and become a regular in Tuchel's side next season as he starts his third campaign as a Chelsea player.
