Doing my research, he bought Merino, Isak, Monreal, Matt Ryan, Zakharyan, Sucic, Kubo in some of his more interesting buys, already quite a bit of hit, but there are plenty of misses that I didn't include.
Loaned Sorloth, Odegaard, Tierney, Andre Silva, Theo Hernandez in, which are pretty successful except Silva who flopped.
His sales is the interesting bit to me. He bought alot of flops, but managed to sell those flops for profit (how?!) and those hits for huge money.
