Liverpool's problem's go a little deeper than the loss of one player.
This Liverpool side is number one in the league for distance covered and sprints, it's no surprise when it comes to a congested period like January their players look burnt out suffering from fatigue and as a result their attacking their moves have become aimless and ponderous possession based probes on the edge of the opposition box instead of Klopp's trademark incisive and direct counter attacking football the hipsters have come to love.
When the composition of the squad beyond the first 11 is already poor you don't need a genius to see how that'll affect performances of the already over relied upon first 11. The buck stops with Klopp ultimately, if the squad poor why not buy in Jan? You telling me there's no players out there who could improve this Liverpool side available in jan?
And before anyone comes out with all that BS about January premiums and the rising costs of transfer fees etc Liverpool are not a poor club, they've never been afraid in the past to spend big and their operating a -£14M net spend currently. Money is there and when CL football, which is vital to making progress, is at stake why not spend?
Would I take Klopp instead of Wenger, no. Klopp continues to exhibit traits that you'd expect of early Emirates Wenger. Such as being too dogmatic with his ideals, lacking in a tactical plan B, trusting in average players, aversion to the Jan window, overplaying, ridiculous statements in the press and maybe too egotistical where as Wenger evolved 2013 onward and become slightly more pragmatic in his management even though he still has plenty of flaws.
