On Boxing Day after young Belgian forward Divock Origi had limped out of Liverpool’s victory over Leicester, Jurgen Klopp was understandably bemused. Never one to mince his words the German declared ‘hamstring’ to be a dirty word. A very dirty word. “It is always hamstring, hamstring, hamstring – that is the intensity of the game and fixtures” he went on to say.

Origi is still out, as are Phillpie Couthino, Dejan Lovren and Martin Skrtel at the time of writing – all with hamstring injuries. Simon Mingnolet and Jordan Rossiter have also ‘felt their hammies go’ this season. And as for Daniel Sturridge, as one wag on Twitter put it he seems to be ‘made of crisps’.

So have Liverpool been unlucky with injuries this season. Have they fared any worse than any other club? And if so, is Klopp’s training regime partly to blame?

Well Liverpool certainly haven’t been lucky, as this article and table posted on BBC Sport last week shows. Only Newcastle have actually lost more days due to injury this season.

Interestingly Leicester and Watford have the lowest number of injured players and both are doing well. The graphic also shows that the ‘top six’ of this injury table (Leicester, Watford, West Brom, Norwich, Swansea and Southampton), i.e. those least affected by injury, have no European commitments.

So do Liverpool’s problems stem mainly from Klopp’s new style of ‘gegenpressing’ (’counter pressing’)? Bad luck is unlikely to be a factor as elite sport so often proves that luck has little to do with winning or losing.

Arsenal’s style is not built on the ‘gegenpressing’ model, though pressing is so integral to the modern game that they certainly work on it. Yet Arsene Wenger has not experienced the same problems with his squad as the other big money clubs and the Gunners are still in the mix for the title.

Graeme Souness is certain that Liverpool’s problems do stem from Klopp’s style. Although the German has said that training isn’t the problem as “there is no training only recovery”, the ex-Liverpool manager is convinced that training is a big issue with the players at Anfield. He said on Sky Sports recently that “It's hard work to do that for 90 minutes. You can do it in bursts. You can do it for an hour, you can do it for 70 minutes, but to do it for 90 minutes is a big demand on your legs.” “It's not a coincidence, five hamstrings. To have them all at one time, I think they have to look at what they're doing in training."

The answer would seem to be somewhere in the middle of those opposing views. If Liverpool really are committed to only recovery sessions between matches then that is a tacit admission that the games are in fact very tough on the legs of their players and their hamstrings in particular.

So Souness is right that 90 minutes of gegenpressing is as tough as it gets but it seems it’s the matches that are causing the Reds’ problems and not the training.

It’s all a far cry from the days when Aston Villa won the First Division using just 14 players in 1981. The game at the elite level is not any tougher but it is a million times faster and that is the difference. One last stat that might prove important in the years to come. Jurgen Klopp signed 43 players during his seven years at Borussia Dortmund. If he does the same at Anfield ‘sound hamstrings’ will certainly be on top of the list given to his scouts.
