Lindegaard dubbed the new Peter Schmeichel travelled to Carrington to undergo a medical and put pen to paper on a £4.2m move from Norwegian club, Aalesunds.
The 26-year-old has been tracked by Sir Alex Ferguson since the summer, with United goalkeeping coach, Eric Steele, making numerous personal checks on his progress.
MEN Sport revealed in July that Lindegaard had been identified as a potential to successor to Edwin van der Sar, who turned 40 last month.
The Dutchman is out of contract at the end of the season and it is becoming increasingly unlikely that he will retire in the summer.
Ferguson also maintains an interest in £15m Atletico Madrid keeper, David de Gea, who he travelled to Spain to watch earlier this season.
Despite comparisons with his countryman, Schmeichel - who enjoyed eight trophy-laden years at Old Trafford - United's former No1 has questioned whether Lindegaard is the right man to fill Van der Sar's shoes.
Schmeichel said: I don't believe he's one they are looking at.
You can look at talent, you can look at young, good players, but you want someone that can go in straight away and give performances in 80 per cent of the games that the No.1 choice goalkeeper will play for United.
Too many goalkeepers have been in and out of the doors at United and I think now the general perception is, for this team to play well and win trophies, that position has to be someone who is of the very, very highest quality.
