Laurent Koscielny is the best defender at Arsenal by some distance, that is a fact that few would argue with.
However, the 33-year-old has an extensive injury history, and that has ruined his game at this point.
Indeed, for most of last season plasters and sheer will power held him together. The Gunners simply can’t rely on the Frenchman long-term, and he needs to be replaced.
They’ll be keen to get his wages off the wage bill while he may fancy a return to France for the end of his career.
