@CC the comparison between Lallana and Sakho simply doesn't work.
Sakho was binned, not for footballing reasons but for personal reasons.
Lallana would only ever have been binned for footballing reasons, similar to Milner. Both were on borrowed time, in the positions they were playing in. That has proven to be fact. Mane has taken Lallana's position and Wijnaldum has taken Milner's. As it turned out, Klopp found a new position for both and extended their stay at the club.
Good management all round.
My biggest mentor is myself because I've had to study, so that's been my biggest influence.
