Ruben Amorim reportedly issued Manchester United outcast Alejandro Garnacho with a harsh 10-word warning ahead of the summer transfer window.
The Argentine, 21, finally completed his move to Chelsea last week, with the two clubs agreeing a £40million deal and the player signing a seven-year contract.
Garnacho made it clear he 'only wanted Chelsea' more than a month earlier, but disagreements during negotiations meant the deal dragged on until the last week of the transfer window. Club officials at Stamford Bridge are believed to have offered the Red Devils a number of players in potential swap deals in exchange for the winger - all of whom were rejected by United officials.
