Petty pride and hurt feelings are not very attractive attributes and should never take part in decision making on any level or in any arena (or personal life).
Haaland was 19 when we were in for him last year. He didn't turn us down because he didn't like us or didn't see us as worthy of his signature. He missed out on him because he felt he was only wanted by the manager and not the club, the players and staff at Dortmund did a great job charming him by sending him PMs on social media telling him how cool it would be if he came there, he was promised a role as the main #9, they gave him the release clause he wanted to be in control of his career and he could continue his recordbreaking debut season in the knockouts of the CL.
I can't see how you can hold any grudges against him for making the choice he did, for half the wage we offered him as well. He wanted the right arena to develop in. He'll come here if we show him we have ambitions of getting back to the top and include him in one of the lead roles. Right now trying to sign him would alone be proof of our ambitions.
He would be the best number 9 ever to wear red if he came here.
