So, very worryingly, note the second last paragraph in that Russian article: A bad start in the Championship and............
"For Slutsky it will be extremely important, in the case of failures at the start (and with an understaffing this is very realistic) not to swim. It is said that during his time with CSKA he resigned four times, and only Giner's patience led to the fact that as a result, with the LAN, the team won three championships, cups and so on. I have a doubt that this Egyptian comrade will be the same subtle psychologist."
So there you have it...looks like Slutz is a big cuddly fragile bear requiring deft emotional handling after a couple of defeats. Papa & Polo Boy are unlikely to be able to provide this.
