Klavan, Grujic, solanke, Keita, Shaqiri, Karius,
All wastes surely? Especially Keita who is never fit.
Klavan cost €5m as a 4th choice centre back, played 39 games over the course of just over 2 seasons and was sold for £2m with the emergence of Gomez.
Grujic was signed for £5.1m at age 21 and has since been on loan. Estimates of value in summer range from £25-40m
Solanke cost £3m and was sold 18 months later for £18m.
None of these 3 can be argued as being a waste of money at all.
The other 3 are more debatable.
Keita cost around £55m and so far has been under whelming. Injuries cost him when he finally looked to be settling into place, but with many years left in his contract, and with the talent he has, he remains a question mark in terms of value.
Shaqiri cost £13.5m and has had limited game time as back up to the front 3, although did score the winners against united. Again, given the limited fee and the intended role as backup, I would argue he has been neutral in terms of value. Neither best, nor a waste.
Karius on the other hand....... An unmitigated disaster. Leaving aside his performance in the CL final, which may or may not have been affected by concussion, he was poor throughout most of the season and never convincing. In fairness he was considered to be the 2nd best keeper in the bundesliga before we signed him, for £4.75m, but still, a total disaster and waste of money.
If these are the worst signings of klopp that you can think of, particularly in light of the successes, I can rest easily with that.
