COPENHAGEN (AP) — Christian Eriksen sent his first public message from the hospital on Tuesday, thanking supporters for their “sweet and amazing” well-wishes after his collapse at the European Championship.

Eriksen remains in the hospital after suffering cardiac arrest during Denmark’s game against Finland on Saturday, when he had to be resuscitated with a defibrillator on the field.

“Big thanks for your sweet and amazing greetings and messages from all around the world. It means a lot to me and my family,” Eriksen wrote in a message that was shared by the Danish soccer association on Twitter.

The message was accompanied by a photo of the 29-year-old Eriksen giving a thumbs up from his hospital bed.

“I’m fine – under the circumstances,” he added. “I still have to go through some examinations at the hospital, but I feel okay. Now, I will cheer on the boys on the Denmark team in the next matches. Play for all of Denmark.”

Eriksen and the rest of the Denmark players have received an outpouring of support from all over the world since Saturday’s incident, including from fans of rival teams.

Denmark coach Kasper Hjulmand said the flood of messages shows that “football is the biggest social phenomenon in the world.”

“It’s the one thing that can unite most people in the world,” Hjulmand said at a news conference on Tuesday. “It brings friendship across nations, race, gender, everything. Football is one big family. … And we see this with all this recognition we get from people all over the world.”

Denmark, which lost to Finland 1-0 after the game was resumed, next plays Belgium on Thursday in Group B. On Monday, Eriksen’s teammates said the midfielder had told them to re-focus on the tournament.

And Hjulmand said he can tell that his players are gradually getting back the right mindset to play again. But he acknowledged that returning to Parken Stadium again, where the players formed a ring around Eriksen as he was getting emergency medical treatment that saved his life, will be emotionally challenging.

“I don’t think they’re afraid to play,” Hjulmand said. “But the normal reaction to a trauma like this, you should know, it’s not only yourself. It’s also your family, maybe your kids, your wife, your parents. So the box of emotions has been opened. I think we took a big step yesterday and I think we’ll take another one today.

“Of course the time until the kickoff will be emotional, and we have to prepare ourselves for that, for entering the stadium again. Getting back to see our great fans. And up to kickoff there’ll be a lot of emotions we have to handle, and then prepare ourselves for when the referee whistles his first whistle. We will be ready to go and fight and play well and do everything for Denmark.”
