Manchester United pulled out of the running to sign then Barcelona midfielder Thiago Alcantara in the summer because of Ryan Giggs' insistence that he would not fit in at Old Trafford.
David Moyes had identified Thiago as the man to fill the void left by Paul Scholes along with Cesc Fabregas.
Moyes was eventually pipped to the post by Bayern Munich to sign Thiago, however it now appears Pep Guardiola only won the race to sign the central midfielder because Giggs thought the Spaniard was not a 'Manchester United player'.
Those claims sound slightly bizarre as Manchester United ended up signing Marouane Fellaini from Everton who does not exactly tick all the boxes when it comes to having the qualities to grace Old Trafford.
However BBC journalist Ian McGarry has today revealed how Giggs vetoed Moyes' move for Thiago.
Speaking to BBC 5 Live, McGarry said on Manchester United's pursuit of Thiago: "I was told that in a meeting between the coaching staff last summer they were making plans to buy players.
"Round the table were David Moyes, Chris Woods, Steve Round, Jimmy Lumsden, Phil Neville and Ryan Giggs. Thiago Alcantara was the subject of discussion as a deal had been concluded and all they were waiting for was a medical to be signed off.
"David Moyes said to his coaches 'what do you think?'
"When they went round the table to Giggs - who was last - he said 'not a Manchester United player' and Moyes said 'sorry I don't know what you mean by that - can you please explain'.
"And then Phil Neville said 'playing for this club is more than being a footballer. It is about your attitude, your mindset and everything in your body must want to live, play and win for Manchester United.'"
Moyes eventually splashed £37.1million on Thiago's international teammate Juan Mata to provide some creativity in Manchester United's midfield.
