Winger Mohamed Elyounoussi admits playing his second season at Celtic on front of no supporters is something he looks back on with "regret".
The Norwegian international has impressed since returning to Premier League side Southampton, netting four goals in seven matches and featuring six times in England's top-flight.
Elyounoussi spent two years on loan at Celtic, winning the domestic treble in his first season. But the second did not go to plan as Rangers ended the Hoops' 10-in-a-row bid.
For the 27-year-old, playing in front of no supporters is what made last season especially difficult for him as Celtic endured a torrid time.
Celtic ended the 20/21 term 25 points off Rangers and without a trophy as St Johnstone won the League Cup and Scottish Cup.
The Parkhead side's supporters have a reputation for creating memorable atmospheres and Elyounoussi admits their absence last term was noticeable.
The former loanee told the Guardian : “When you score in an empty stadium, it’s like scoring in a garden.
“It is so quiet and you do not actually feel anything. That was my only regret. It was a shame I couldn’t feel it [the atmosphere].
"We played in a [Scottish] League Cup final against Rangers and it was electric. The pitch was shaking. It was something I never had before.”
