After finalising his move to the Premier League champions earlier this month, Haaland has since been away on holiday with Botheim, who is currently a free agent after leaving Russian club Krasnodar following the invasion of Ukraine.
Botheim, a 22-year-old striker who recorded seven goals and six assists in 14 games for Bodo/Glimt in the first half of last season, has been linked with a move to Ibrox, while Marseille are also believed to be in the race for his signature.
Rangers supporters have adopted the anthem 'I'm Feeling It (In The Air)' by The Sunset Bros and Marc MacCabe, and the Scottish giants played the song at Ibrox after victories last season.
The potential arrival of Botheim in Glasgow could cast doubts over the future of Alfredo Morelos, who has just a year remaining on his contract and has been linked with a move to Sevilla. body check tags ::
