It has been three strikes and you're out for Alejandro Garnacho at Manchester United

It was seven years ago that three of us were beckoned to the doorframe of the Levi's Stadium press room in San Jose. Jose Mourinho stood in it.

Mourinho stressed to the three of us he was prepared to let Anthony Martial leave Manchester United. Martial's agent, Philippe Lamboley, had outlined his intention to move only a month earlier.

If a player wanted out, Mourinho was never going to stand in the way. But Ed Woodward did. He blocked Luke Shaw's sale that summer as well. Martial and Shaw would sign new contracts within the next six months.

Martial outstayed his welcome at United and was released after nine years last year. Shaw is 11 years and counting. This is what happens when you undermine the United manager and erode the role's authority.

So United supporters have to be sanguine with Ruben Amorim's decisive call on Alejandro Garnacho. Garnacho was told on Saturday he can leave.

It was three strikes and you're out for the 20-year-old. Garnacho was dropped for the Manchester derby in December on account of his attitude and skulked down the tunnel following his first-half substitution against Ipswich Town in February. He paid for a team meal by way of an apology.

Garnacho is still so young but should not be as juvenile as he is on social media. Erik ten Hag had to give him a ticking off last season over a tweet he liked from an account criticising his substitution against Bournemouth.

When a 20-year-old sounds off about a "s**t season", criticises the manager's selection and casts doubt on his future, he should be ushered towards the door marked 'exit'. Garnacho was on raw form in the San Mames mixed zone and he was not the only United player who used the platform as an unburdening.

Yet this is not the first time he
