New Manchester City signing Erling Haaland is a target for sportswear giants.

The Norweigan's £1m-a-year boot deal with Nike ended earlier this term and he chose to keep his options open until he switched clubs, says The Sun.

Haaland will earn £375,000-a-week with City, but will boost that figure significantly this summer through endorsements.

Puma, who already sponsor City's shirts at £65m-a-year, are understood to be in a bidding war with rivals Adidas to sign the 21-year-old star.

Both German boot firms want to tie him up for the next decade.

The exposure of playing in the Premier League will increase Haaland's earning potential, with offers worth £5m-per-year being discussed.

Haaland signed off his BVB career with a goal and received a guard of honour in his side's 2-1 home win over Hertha Berlin earlier.

He later posted an emotional video on social media thanking Dortmund fans for their support.

In the video, Haaland said: "Dear BVB fans, I had unforgettable years at Dortmund.

"Thank you for the great support, you will always have a place in my heart. All the best to you all."
