Luis Suarez says he was determined to leave Barcelona with his "head held high" last summer after being "disrespected" by the club ahead of his move to Atletico Madrid.

The Uruguay striker left the Nou Camp in acrimonious circumstances in September as Barcelona's second-highest goal-scorer of all time, having scored 198 goals since signing from Liverpool in 2014.

Suarez, 34, had one more year to run on the contract he signed with Barcelona in 2016, but was told by new head coach Ronald Koeman that he was not part of his plans.

The striker has since scored 14 goals for Atletico Madrid after moving to the Spanish capital for £5.5m, with Diego Simeone's side 10 points clear at the top of La Liga.

The former Liverpool forward says he rejected the chance to sit out Barca's pre-season while his move was finalised and did not speak to now-former president Josep Maria Bartomeu over his exit.

"It was tough because of the way I was disrespected, but I wanted my children to see me leave the club with my head held high.

"When the time came to tell my children about the move, it was very difficult. They're older now and sensed there was going to be a change," Suarez told Onda Cero.

He added: "There were some very tough moments surrounding my departure from Barcelona. There were rumours that were eventually confirmed and that's what hurt me the most."

"Koeman called me and told me I wasn't in his plans. I accepted the decision, but I told him I had a contract and the club would have to sort it out. I was given the option not to show up for pre-season, but I said that I was still under contract and that I was going to show up.

"Nobody explained it to me properly. I didn't get to speak to Bartomeu. My lawyer took care of that.

The striker admitted that his move was very much needed to protect his pride.

"Seeing how Barcelona are doing does reassure me in some way. I could've stayed put and been paid, but I still believed in my ability. I knew that if I stayed I'd be slated the moment there was a hint of bad form. I needed a change for my pride.

"The first thing I said in terms of negotiations with Atletico was that I didn't want to do anything until I had left Barcelona. There was a lot of talk about Juventus, but plenty of clubs were interested. I kept moving forward with my Italian passport because it was something I'd been doing for a year."

Suarez also spoke about his close relationship with Lionel Messi and was upset to see details of his former team-mate's contract being leaked in the Spanish press.

"I arrived [at Barcelona] one day and started to have mate [traditional South American drink] with Messi. We struck up a great rapport and became like a family. Our wives began to have a fantastic relationship, which also helped strengthen our own wonderful connection," he said.

"I don't understand how someone could be evil enough to make something as private as Leo's contract public, considering everything Messi has done. No footballer has ever given as much to one club.

"Only four or five people could've known about the contract, but I have no idea who it could've been. I spoke to Messi two years ago about how we were finding it harder and harder and maybe wouldn't be able to retire in the way that we wanted."

Suarez also dismissed suggestions of a strained relationship with Antoine Griezmann, who joined Barcelona in the summer of 2019.

"We had a good relationship with Griezmann at the start," he said. "We were open with him and met up away from football. You can't come out to deny everything because it would drive you crazy."
