"Hello everyone. Big thanks for your sweet and amazing greetings and messages from all around the world. It means a lot to me and my family," Christian Eriksen posted on Instagram on Tuesday morning.
"I'm fine - under the circumstances. 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. Best. Christian."
The Dane was clinically dead for some time but doctors managed to bring him back to life.

While it was reported that Eriksen is now stable, Denmark's team doctor Morten Boesen has come out to state the extent of what happened.
"He was gone," Boesen said in a press conference.
"How close were we? I don't know - we got him back after one defib... so that's quite fast."
Interestingly, doctors still don't know why the cardiac arrest happened to Eriksen.
"Eriksen's preliminary tests have given good results, but he will have to undergo further tests. None of us knows what happened," Boesen added.
