€120m is a fair-price for a player of Sanchos' quality and age. I'm not surprised Dortmund are playing hardball, especially with 3 years left on his deal. He'll go this summer or the next, same with Haaland who I believe has a €75m clause in 2 years time I believe?
It's just that the chances of us signing Sancho this summer is a lot higher than the next, where they'd be a lot more competition for his signature. There are times, when we should have backed away from certain transfers due to obscene fees involved, see Fred, Maguire, even AWB. But, this one we should pay up, it will be worth it in the long run.
