Carlos Carbonero has completed his year-long loan move to River Plate and described the switch as a "dream".
The winger, 22, was expected to leave Estudiantes LP on loan again following his return from Arsenal de Sarandi and the Colombia international is extremely pleased to have joined the Argentine giants on a temporary basis.
He told the club's official website: "I'm very happy. It's a dream to be at a club as large as River Plate. And I'm also happy that the club chiefs and the coaching staff trusted me enough to see that I can help the team.
"When I was told that there was interest in River for me, I did not hesitate for a second. It is a very important step in my career and now I want to enjoy it to the fullest.
"Now I want to get fit physically and work with my new team-mates and the coaching staff to get ready for the second half of the season and the Copa Sudamericana."
River have also signed experienced attacking midfielder Jonathan Fabbro for the remainder of the season from Cerro Porteno, with the player determined to make the most of his "prime" years.
"I hate talking about money, but [I] left a lot to come to River," he told radio station Rock and Pop.
"I feel good about my football, but I want to get fit physically. I believe I am in the prime of my career, so it will be a unique experience for me. I have great faith and confidence in myself."
