Alexis, whose whole summer was abuzz with a potential move to Manchester City that ultimately broke down, had hoped to see his side bounce back from a 3-0 defeat to Paraguay last week.
It was not to be, however, as a solitary penalty from Juan Arce saw Chile slip into sixth, one spot behind Argentina, who currently reside in the only play-off place.
And now “tired” after what has been an emotional few months for club and country, the 28-year-old took to Instagram to vent his frustration at what he feels has been harsh criticism from the press.
Y LLEGA EL MOMENTO EN EL QUE TE CANSAS . Te cansas que te critiquen con razón y sin razón, te cansas de que te quieran ver derrotado , te cansas de decirte a ti mismo "una vez más me levantare" después de llorar tras una derrota, y te cansas de decirle al mundo y a las personas que están contigo, que todo va bien . Y lo peor, que nunca nadie se da cuenta de cómo eso te hace sentir ... tengo el dorsal de chile y es una responsabilidad enorme, por eso me da pena que periodistas y gente mala critique sin saber ...
“And there comes the time when you get tired,” he said.
“You get tired when you are criticised with or without reason, you get tired when people want to see you defeated.
“You get tired to tell yourself 'I will get up again' after crying about a defeat, and you get tired telling the world and the people that are with you that everything is okay.
“And the worst thing is, no one ever realises how that makes you feel... I have Chile's number 7 and it is a huge responsibility, that's why it is a shame that journalists and bad people criticise without knowing.”
Sanchez has been included in Arsenal's 42-man Europa League squad and will next face Bournemouth in the Premier League on September 9 at the Emirates.
