Klopp "Normally the system I love is one where all players thrive collectively and the other helps another go the next level. When we bought Salah, many said Mane has gone down. Salah scored 43 goals, Mane didn't have impressive figures than when he was the sole focus. So people will say buy this one and that one. I have people come for tea at my house, we talk. I ask them if I buy that player and Mane and Salah what I have already drop because I must accomodate the player, can I say I am strengthening? You can buy players and not be strengthening. I thought Salah did more when Chamberlain was around, and Chamberlain wasn't there last season. I now understand my players, I now know their potential and which player helps them move up a gear. I thought also Mane did well with Lallana. So now you see, this is it- if I get a new player and then Salah, Mane and Firmino drop and that player scores 30 goals, have I improved the team?"
