Dinamo Zagreb confirmed on their Twitter account that the striker would be playing in their colours for the season ahead, and will wear the number nine jersey.
This is the 20-year-old Chilean's third loan move away from the Red Devils since joining the club in 2012 from Universidad de Chile. He has had previous loan spells at Wigan Athletic and Real Zaragoza, but has never made his senior debut for United.
With the forwards who are currently ahead of him in the pecking order, it's no real surprise that United have opted to ship Henriquez out on loan again.
Robin van Persie, Wayne Rooney, Danny Welbeck, Javier Hernandez and now maybe James Wilson are currently between him and the starting spot in Louis van Gaal's side.
What's surprising is that he hasn't made a permanent move away from England yet. If you are a youngster and you are going to make it at a big club like Manchester United, then at 20 years old you should be pushing for a first-team spot at different team.
Welbeck was scoring goals in the Premier League for Sunderland at that age, and Wilson, just 18, is playing phenomenally well in the reserve team at present.
Henriquez hasn't helped himself by being disappointing in each of his two loan spells. At Wigan, he had the opportunity to show what he could do in England's top tier, but he made only four appearances for the Latics and scored just a single goal.
His spell in the Spanish second division was a little better as he made 26 appearances for Zaragoza in the 2013-14 season, but managed only six goals, which isn't a great return from a striker.
It was thought that Henriquez would make a return to his former club Universidad de Chile, but United manager Louis van Gaal reportedly blocked the move, stating that he had not evaluated the forward enough to be able to sanction it.
