Radamel Falcao has hinted at staying at Manchester United beyond this season when he was unveiled at news conference alongside fellow new signing Daley Blind.
The duo will be hoping to help turn around Manchester United's fortunes after a slow start to the season which has seen them pick up just the two points from their opening three Premier League games.
Falcao said: "I am very happy to be here. it's a big challenge for me, for my career and I always dream to be in a club like Manchester United.
"This is a knew process, a new team. I think Manchester United build a big team this season and in future seasons and I will like to be here and to be part of this project."
The striker also fielded questions about a long-term knee injury he has recovered from, but seems confident it won't hold him back at his new club after signing on a season-long loan.
"I feel well. I started to play two months ago with Monaco and I improved in the last month, a lot. I score goals and that is important to strikers. I am confident with my physical form and I am comfortable with my knee."
Fellow new signing Daley Blind seemed relaxed about whatever position Louis van Gaal wants him to play and added that the Dutchman was a big factor in his decision to leave Ajax for United.
He said: "He gave me a lot of trust during the world cup and the qualification games. I'm happy to work again with the coach I learn a lot from him and I hope I learn more."
Van Gaal was asked how he could fit all the new players he brought to the club into the side, and said this kind of window can give younger players a chance.
"We bought five players and one player is on loan here, maybe we can buy him next season. We let go 14 players, so how to fit in these players is not so difficult, I think.
"When you don't let players go to another club you are never allowed to give a youth player a chance, because of this policy we give youth players a chance. The question is if they take the chance. It's, of course, more risky but I think it's the only way to do it."
Van Gaal is confident his new signings can improve on the side's stuttering start to the season which has seen United pick up two points from their opening three league games.
He added: "They have to perform our philosophy and that philosophy is not so easy to perform, we've seen it already. I think the players we have selected shall do that better."
