ERLING HAALAND’s transfer to Manchester City has sparked a £50m boot war.
Norweigan’s £1 million a year boot contract with Nike ended earlier in this period and he decided to keep his options open until he changed clubs.
Haaland will earn £375,000 a week with City but will significantly increase that figure this summer through endorsements.
Puma, which already sponsors City shirts for £65m a year, is understood to be in a bidding war with rivals Adidas to sign the 21-year-old star.
Both German boot firms want to hire him for the next decade.
The exposure of playing in the Premier League will boost Haaland’s earning potential, and deals worth £5m a year are being discussed.
Haaland closed out his BVB career with a goal and received a guard of honor in his side’s 2-1 home win over Hertha Berlin earlier.
He later posted an emotional video on social media thanking the Dortmund fans for their support.
In the video, Haaland saying: “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 everyone.”

Another social media post read: “It has been nothing but an honor to wear this jersey.
“At BVB I had memorable moments, met special people, not to mention a fan base that has always been our extra man on the pitch.
“The Yellow Wall is really amazing. I will never forget any of this!”
Haaland scored 86 goals in 89 games during his time in Germany.
He officially joins Man City on July 1.
