If signing these Laportes and Sanes at all (why putting this french é letter since he was born in Germany and even plays for their NT and it doesn't even exist in their alphabet?), then sing them while they're u20s and/or on youth contracts. Laporte was already considered as a talent in as a 16-17 year old, Sane played vs us in Youth League just last february. And developed tha tmuch since. Being a bit offtopic, but that's so disgusting to see where Barker is now, Manuel and 1st teamers should've treaten him better.
Anyway, it's such an awful and money-bag transfer strategy, to buy players for 60m euro that we could've buy much earlier for the positions we already have our own youngsters at.
