Christian Eriksen said he feels "fine -- under the circumstances" in his first message to fans since suffering a cardiac arrest in Denmark's opening match of the Euro Championship.

Eriksen is still in hospital awaiting further tests as they seek to determine what caused his cardiac arrest. But in his first official communication since collapsing, Eriksen said: "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.

"I'm fine -- under the circumstances. I still have to go through some examinations at the hospital, but I feel OK. Now, I will cheer on the boys on the Denmark team in the next matches. Play for all of Denmark. Best, Christian."
