Arsenal forward Alexis Sanchez has issued a long message on Instagram saying he is 'tired' of the criticism he receives when on international duty with Chile.

Chile have enjoyed great success in recent years but qualification for next summer's World Cup is in doubt after back-to-back defeats over the last week.

A 3-0 loss at home to Paraguay last Thursday was followed by a 1-0 defeat in Bolivia on Tuesday night.

Chile sit sixth in South American qualifying for the tournament in Russia with two rounds left and only the top four qualifying automatically.

Sanchez was criticised in some quarters after the Paraguay loss, which came on the same day as a potential transfer from Arsenal to Manchester City fell through.

The forward has now posted a photo on Instagram of himself walking off the Wembley pitch with a Chile flag around his shoulders after the FA Cup final win over Chelsea.

Alongside the photo, he wrote (translated from Spanish): "And the moment comes when you get tired.

"You get tired of them criticising you with reason or without reason, you get tired of them wanting to see you defeated, you get tired of saying to yourself I'll pick myself up one more time after crying after a defeat, and you get tired of saying to the world and to the people who are against you that everything's OK.

"And what's worse is that no one ever realises how this makes you feel.

"I have the Chile number seven on my back and it's an enormous responsibility, so it makes me sad that journalists and bad people criticise without understanding."
