Off the top of my head, under Klopp we have bought Karius, Klavan, Matip, Robertson, Grujic, Wijnaldum, Mane, Salah & Solanke.
Only Wijnaldum, Mane & Salah cost big money and all look excellent buys along with Matip. There's only 2 duds in Karius & Klavan and neither of them are the type of disasters we have become accustomed to over the last years under successive managers.
In the process, Klopp has turned us into a thrilling attacking force, one of the most attractive to watch in Europe but with obvious flaws in defence. Any criticism is pretty harsh I would say, we just need to back him to fix the defence and add some depth to the squad.
Starting now, this week with 2 or 3 big signings.
