I don't really understand the reasoning behind Frimpong, Kerkez I get because he has time to be molded into what Slot wants him to be, he can be industrious, he just needs to adapt from playing in a different system. Frimpong played a different system too but he's so physically slight and will always be a target for the gaps he leaves and for his lack of height at setpieces, and the lack of protection from Salah. The only way it makes sense is if he will actually step in for Salah on occasion, but as already covered, that's not going to happen any time soon.
Salah shouldn't be anywhere near that game tomorrow, neither should Konate.
