There were troubling scenes when Eriksen collapsed to the ground with no one around him just before half-time of the Group B fixture in Copenhagen, with team-mates forming a protective circle around him as medical personnel rushed to his aid.

The world of football rallied around in support of Eriksen, and Inter chief executive Giuseppe Marotta offered further good news by revealing the former Tottenham Hotspur star had messaged Inter's group chat on WhatsApp.

"We watched the images on TV that suggested something dramatic was happening, which unfortunately we have also seen on Italian pitches before," Marotta said.

"The players are very close and we all immediately communicated with each other after seeing those images. We didn't want to be invasive and so tried to respect his [recovery] once we had been reassured.

"I can only say that 10 minutes ago Eriksen himself sent a message in our internal chat and this confirms the bond between the players."

Asked if he had an update on Eriksen's condition, Marotta added: "We're optimistic about Christian's condition, Denmark's staff told us that the situation is under control.

"I cannot enter into the merits, the player is under the control of the Danish national team. The best thing I can tell is that Eriksen responded positively, the intervention of [Simon] Kjaer and the doctors was very important."

Denmark team doctor Morten Boesen spoke about the incident, saying: "We were called on the pitch when Christian fell over. 

"I did not get to see it, but it soon became clear that he had fallen over. When we got there, he was lying on his side and was breathing.

"We felt the pulse, but pretty quickly the picture changed, and then we started life-saving heart treatment."
