If he signs a five year contract and only stays those five years, that is fine with me. If in the fourth year someone comes with a big check, that’s fine too. I repeat, it’s unrealistic to expect ANY player to come and stay the rest of their career here
However, a superstar player that is able to compete at the highest level at their current club AND has every reason to stay, not only for the sporting reasons but because they make more money that way. Messi stayed his entire career in Barcelona and is a rich man. Cristiano Ronaldo with 6 years at United then 9 years in Madrid, the same. Anyone who thinks Raiola doesn’t understand what every other agent understands, besides overestimating his own role in Haaland’s career planning, is also underestimating his own aptitude
