Defender Benjamin Mendy has returned to training with the team and is expected to be fit in two or three weeks. But he did dismiss suggestions that he asked the grass to be left long for the 2-1 victory over Liverpool.
Norwegian tabloid Verdens Gang, quoting unnamed sources, reported that a demand for ransom corresponding to 9 million euros (US $10 million) had been made, payable in the Monero cryptocurrency.
Mr Broeske said "those behind have chosen to communicate digitally and we have had no other type of contact". Police have received no signs whether Falkevik Hagen was still alive, "but we haven't either received any sign that she is not alive", he added.
It said Mrs Hagen appeared to have been abducted from the bathroom of her home and that there had been "limited dialogue" with the alleged kidnappers over the internet. "It is demanding and exhausting to be in such a situation over a long period of time", he said.
"Our main theory is that the victim was kidnapped by unidentified perpetrators at her home" in Lorenskog, about 20 kilometres (12 miles) from Oslo, he said. The report also explains that Norwegian police have widened the investigation to include Interpol and Europol.
Through his lawyers, he's decliend to comment on his wife's disappearance.
