The 19-year-old Brazil-born Spain Under-19 international agreed a temporary move from Benfica just a month after joining from Real Madrid. Moreno is now looking forward to gaining some experience in the Barclays Premier League.
"I'm very excited at making such a big step in coming to the best league in the world," he said. "The manager has known about me for a long time and because he has been pushing for a transfer to bring me here then it motivates me a lot."
He continued: "I want to give back to the club all the confidence that they have shown in me so I'm going to do my best to help the team to reach their objectives.
"I'm very much impressed with the stadium and the training ground. I already knew that Bolton are well established and respected in the Premier League but now I have an even better idea of how big a club this is.
"I want to thank everyone at the club for helping this transfer become possible and I'm looking forward to next Monday when I get the chance to meet all the players and start work."
Moreno will link up with former Real club-mate Marcos Alonso at the Reebok.
"I played with Marcos last season - he is a great player and a great friend of mine," he added. "Hopefully he will help me adapt to the English way of life because he has been here a month already."
Bolton assistant manager Sandy Stewart believes Moreno's versatility will fit in well at the club.
"He is a quick, exciting young player who can play up front and in wide positions," he said. "We are looking forward to working with him and we are confident that he will bolster what is already a strong squad of players."
