Fair point - I should have explained further. Kewell had one serious injury whereas with Naby it's been a succession of niggles and, when the latter happens, it tends to suggest that part of the problem may lie in a lack of stomach for the fray.
I'm not sure that follows at all, especially when you consider the type of injuries he's sustained and the quality of our medical team.
Of course it is a supposed aphorism in rugby that more injuries occur from pulling out of tackles than going in full-blooded, but having played rugby for many years I seriously doubt that, it's basically just said to cajole players into committing to tackles. For Keita it just seems that his body is not built for the physicality of the PL. Lots of niggles and minor, as well as more serious, injuries (15 in 3 years, ignoring Corona) however very little at RBL though a few injuries at RBS in Austria maybe a pointer.
There were a few 1 or 2 games lost to various niggles / illness (9 games) and 6 games to Corona. Then we have 13 games to an ankle injury (see below), 3 x groin injuries (11 games) and 6 x Hamstrings (27 games missed). This doesn't point to a lack of stomach but susceptibility to muscle injuries (maybe caused by the type of tactics Klopp employs, Naby being well known as a strong presser so short-sharp spurts).

Perceptions can be deceptive. The idea that Keïta somehow isn’t tough enough doesn’t take into account the punishment that he has withstood. Against Manchester United, he was treated by the physio on the pitch on three occasions, including the tackle to which he eventually succumbed, that saw Paul Pogba sent off. All three of those challenges were reckless at best and dangerous at worst. It was a symptom of Manchester United’s inability to handle his intelligent movement, tigerish pressing and passing range, and so they decided to start kicking him like a bunch of eight-year-olds.
While being stretchered off at Old Trafford, no one would have predicted that Keïta would start the next league game six days later. He may have been lucky that his standing leg wasn’t planted as Pogba came through it, but to even line up against Brighton showed precisely the kind of toughness that many believe he doesn’t possess.
This latest injury owes as much to the overall fitness of the group as it does to Keïta. If Klopp had more midfielders to choose from, the suspicion is that the Guinean would have had more time to recover from his multiple knocks in Manchester. A hamstring problem can often be traced back to a heavy workload, and
it appears starting his ninth game in 27 days for club and country was a step too far.
