Some of yous really have selective memories. We signed Mane when at the time the AFCON was taking place in January, fully aware that he would be gone for that period. we followed that with signing Salah, when again at the time AFCON was still scheduled to take place in January [that change took place later].
Aside from that, I am perplexed why anyone would think that Klopp would sell a player because he won't be able to use him for a month. Considering he waited an entire year to work with Keita for instance, waited a year for Ox [and not signed his replacement],etc..
