Another reason why Garnacho choose Chelsea over Bayern Munich is because he wants Manchester United to see how he is going to succeed in Chelsea, Manchester United and Chelsea have a good relationship but they are big rivals in the pitch, if you observe many young Manchester United players like Sancho, Rashford, Antony and Garnacho they are not happy with Manchester United and they prefer to be the team rivalry in the Premier League instead of going to another team, Rashford wish to join Aston Villa on permanent but they did not sign him.
Garnacho going to Chelsea doesn’t mean he is going to succeed, he might even get sold by Chelsea if he did not play well in one season, Garnacho is still young and he can still learn but go in to Bayern Munich will also help him even when he has not been fit to perform well, it is not a bad thing to sign for Chelsea but Chelsea is not a team that allow players who are not performing well to spent more than two seasons.
As it stands now nothing has materialize for now, if their is a significant development concerning his potential move to Chelsea, it will be all over the internet and garnacho that I know would have flaunt it or drop a hint for people to know that something huge has happened already, but as for now nothing, they are still at the negotiating table, I sees this deal happening very late in the transfer market like the last day or the day before the last day, because Chelsea will surely sign a left winger before the close of the transfer market this month ending.
What I think they are doing is quite normal, by letting the transfer to go to the closing stage of the transfer market so that Manchester united will eventually slash the price placed on him since he can't stay back at the club considering the fact that the player no longer want to play for the team again, so the deal might have, but it will be very late .
