Manager Arsene Wenger said on Friday that Arsenal were responsible for striker Alexis Sanchez missing a drug test on the day he completed his move to Manchester United, and that the player’s absence had been down to special circumstances.
Sanchez, 29, was due to be tested at Arsenal’s training complex on Monday but had already travelled to Manchester to complete a swap deal that saw Armenia international Henrikh Mkhitaryan heading the other way.
