Lionel Messi has taken aim at Barcelona in his farewell message to Luis Suarez.

The latter has been shown the door at the Nou Camp, joining Atletico Madrid in a cut-price deal this week.

Messi, though, will be staying put after Barcelona blocked his exit this summer - despite the club icon publicly admitting he wanted a new challenge.

The Argentinian clearly isn't over it either, taking aim at the La Liga giants on Instagram, saying 'nothing surprises him anymore' after Suarez was booted out the door after Ronald Koeman's arrival.

"I was already getting the idea but today I entered the locker room and the card really fell," Messi wrote alongside an Instagram post of himself and Suarez.

"How difficult it is going to be not to continue sharing the day to day with you, both on the courts and outside.

"We will miss them so much. It was many years, many mates, lunches, dinners ... Many things that will never be forgotten, every day together.

"It will be strange to see you with another shirt and much more to face you.

"You deserved to be fired for what you are: one of the most important players in the club's history, achieving important things both as a group and individually.

"And not to get kicked out like they did. But the truth is that at this point nothing surprises me.

" I wish you all the best in this new challenge.

"I love you very much, I love you very much. See you soon friend."

Suarez leaves Barcelona as the club's third-highest scorer ever.

But the Uruguayan says he expected to leave the club after Koeman's arrival, as the Dutchman looks to overhaul the Catalan side following last season's dismal conclusion.

"I leave with the feeling that I have fulfilled expectations," he said.

"I expected it because it had been said already before the coach told me but I can accept it.

"Players sometimes need a change, the club needed a change and this case the coach didn't want me."
