Stand out in what way?
Young, relatively unknown, cheap.
It's not that difficult to see the difference in the type of signings Walsh wants.
Gueye, DCL, Lookman, Vlasic, Sandro, Onyekuru, Pickford all fit the mould of young and cheap. (Apart from Pickford, but looks worth the money and not overpriced in today's market)
Then the signings rumoured to be more pushed by Koeman.
Bolasie, Williams, Schneiderlin, Stekelenburg, Sigurdsson, Keane, Klaassen, Rooney, Martina. There's a distinct difference between the 2.
As I said though, could be complete bollocks and Walsh actyally sanctioned them all, good to debate it though.
