Clubs splash money in the form of salaries and bonuses to grab players on their shopping list.Haaland can switch to a bigger team in order to earn more.There are many who deserve more than what they earn right now and Borussia Dortmund's Erling Haaland is at the top of that list.Unlike Kylian Mbappe (PSG), Alphonso Davies (Bayern Munich) and many others, Haaland isn't among the highest-paid players in Europe.Right now he earns about £141,000/week. Should Haaland be sold by Dortmund, his weekly wages will skyrocket at a bigger club. As the 21-year-old is tipped to be the next big thing in football, he might finally earn the same amount of money as legends of the game like Cristiano Ronaldo and Lionel Messi. For that to happen, he will have to be part of a bigger and richer team like Real Madrid, PSG, Manchester City or Barcelona.#4 Career growthEven though the Bundesliga is one of the top 5 leagues in Europe, fans don't consider it the toughest league to play in. Haaland can prove his worth by playing in a different league.At Dortmund, Bayern Munich is the only practical threat that remains in terms of domestic competition. The Norwegian should move to a competitive league that will test him. With the abilities he possesses, Haaland would be unstoppable if he raises his game against tougher opponents. A bigger team will also bring him better coaches and teammates, a perfect mix for any stone to turn into a diamond.
