All of Sp**s' signings have been on point since Poch took over. Alli, Davies, Aurier, Dier, Trippier, Wanyama, Alderwiereld, Lucas Moura and even Sissoko has some uses. They're record in the market considering their budget and wage bill is absolutely phenomenal. Think Janssen is the only major flop.
Sissoko at 30m not sure if you can count him as a success tbh. Davinson Sanchez and Son however....
