Erling Haaland has treated his girlfriend to an ultra-rare £330,000 handbag that can only be purchased via auction. 

His partner, Isabel Haugseng Johansen, took to Instagram to upload pictures of her holding a diamond-encrusted Hermès Birkin 25 Himalaya Niloticus Crocodile handbag on Wednesday.

The item from the world-renowned fashion house is not available to buy via its online retail site - instead being advertised for that price at auctioneer Madison Avenue Couture. 

In her posts on the social media platform, Isabel can be seen sporting a long orange dress to go with the designer handbag. 

A video in the sequence shows her filming clear blue skies and equally crystal seas in an unknown location aboard a boat. 

She can also be seen in a group shot with the Manchester City striker and his brother Astor as the group were seen smiling for a photo. 

Isabel, who is a footballer herself, is believed to have met Haaland at the youth academy at Norwegian side Bryne, who they both played for. 

They started dating when he was at Borussia Dortmund, with Isabel making frequent trips to visit him.

Haaland joined Bryne at the age of five and spent more than 10 years with the Norwegian side before later having spells at RB Salzburg, Dortmund and Man City.

Despite previously having no social media presence herself, Isabel has amassed over 100,000 followers since opening her own Instagram account in November last year. 

She had initially kept a low profile on the account, uploading pictures of homemade recipes. 

However, Isabel has posted several pictures of her and Haaland together following the conclusion of the Club World Cup. 

The Citizens striker has been enjoying some well-earned time off after a gruelling campaign which was extended due to the tournament in the United States. 

The 21-year-old was not present in the US for the Club World Cup and was rather cheering on Erling from home as he scored three goals in four games.

As a result, Pep Guardiola's side will only have one pre-season friendly - against Palermo on August 9 - before their Premier League opener a week later which sees them visit Wolves. 

Pictures of Isabel with the extremely rare fashion piece come after she was seen on holiday with Haaland in Rome earlier this month. 

The pair were seen attending the Dolce & Gabbana Alta Moda fashion show together on July 14. 

The 24-year-old was seen wearing a tailored white two-piece suit which he layered over a crisp white shirt.

Haaland completed his outfit with a pair of brown suede loafers and black sunglasses while Johansen wore a nude sheer wrap dress, layered over gold shorts and a matching bra.

As the couple arrived hand in hand for the event, which was also attended by actor Christian Bale, Haaland was seen raising his left hand in a greeting.

The Norwegian striker has been an ambassador for Dolce & Gabbana since 2023, after striking an endorsement deal worth up to £2m with the Italian brand. 

They were spotted on holiday in Rome just a week after jetting off to the popular Spanish island of Ibiza. 

There, the couple were seen on a yacht alongside Isabel's mother and their child, who was born last December.

The couple have been very private with their child and they are yet to publicly announce its gender or name.
