Lionel Messi called the 22-year-old "spectacular" and "extraordinary" after his two goals against Croatia helped Argentina reach the World Cup final.
Lionel Messi and Kylian Mbappe are the top two goal-scorers in the world.
Argentina will play France in the World Cup.
Messi said that nobody imagined thatJulian would have the participation and importance he has shown.
He has given us great help.
Messi has confirmed that this will be his fifth and final World Cup, making him the most talked about player in the tournament.
He has scored five and created three of Argentina's 12 goals, but his contribution to the team goes unrecognized.
Argentina lost to Saudi Arabia and beat Mexico in the first two games of the tournament, with the coach preferring Inter Milan's Lautaro.
He scored the next two goals himself after being brought down for Messi's first goal in the semi- final victory.
He was amazing during the World Cup and also on Tuesday. He was the one to run everything. He fought for every chance he got. He deserves everything that has happened to him because he is a nice guy.
The River Plate player was signed by Manchester City for 17 million euros.
He agreed to a five-and-a-half-year deal with City, but stayed at the Argentine champion until July.
He has made 12 appearances in the premier league this season and scored three goals
The work-rate is unbelievable, according to a former Argentina and City defender.
He's playing with Lionel Messi and he seems to be telling him not to run. He said he would do it for you.
To do that, you need a big heart. He was on the bench at the World Cup, but he's been great.
"To come on to this stage and put in that type of performance, in that moment for his country, is incredible."
Fans of Manchester City will be excited by what is to come.
He has scored seven goals. He is the second player from Argentina to score four goals at a World Cup while he is young.
He is the youngest player to score more than one goal in a World Cup semi-final since Brazil legend Pele did it in a 5-2 win over France.
