Very few Arsenal fans would have wanted to put money on Alexis Sanchez still being at the club after the end of the transfer window.

The Chilean is in the final year of his contract and has made it patently clear he will not be signing an extension.

Earlier in the summer, he announced in the Chilean media that he wanted to play Champions League football and as we all know, he won't be getting that at his current club.

Arsenal almost looked ready to relent and sell him to Manchester City when their Premier League rivals offered £60million on Deadline Day.

Once Thomas Lemar had rejected the Gunners, however, there was no way Sanchez could leave without a replacement.

Granted, the 28-year-old hasn't exactly been the consummate professional during the saga, but you have to feel a bit sorry for him.

The three years he's spent at Arsenal have been frustrating other than the two FA Cups in 2015 and 2016.

Whatever you think of his attitude, a player like Sanchez deserves to be at a European giant, and it's clear the fact he hasn't got his move has genuinely upset him.

Sanchez takes to social media 

On Sunday, he finally broke his silence and voiced his frustration by posting a series of quotes, which he's since deleted. Luckily, they've been brought to our attention by Goal.

“When the world reminds you of your defeats, remind them of your unforgettable victories," the first read.

“A winner is just a loser who tries more than once," added the second.

The third: “What you do matters, but the reason you do it matters much more.”

And finally, he reflected: “You will realise that what today seems like a sacrifice, will end up being the greatest achievement of your life.”

We've all got those friends on social media who feel the need to post these little snippets of inspiration, but it's left fans wondering exactly what he was talking about.

His transfer misery was compounded by Chile's 3-0 home defeat to Paraguay in a World Cup qualifier, so, all in all, it's been a pretty tough week for the forward.

All Arsenal ask of him now is that he remains "100% committed" as Arsene Wenger said he would for the remainder of the season, by which time he'll be able to walk out of the Emirates on a free.
