Ron Vlaar's latest injury suggests the Aston Villa star is not be the right man for Arsenal and Manchester United to pursue during the upcoming transfer window.
The Dutchman is reportedly on both side's wishlists, however, there are likely to be other targets who would offer a better option for them.
Although Vlaar may offer a cheap choice to either side he may not be reliable enough in terms of fitness to be considered a viable transfer target.
Vlaar has had a history of injury problems during his Villa career and already has had to sit out for part of this season with a calf complaint.
Although this current knock, which he picked up over the international break whilst training with Holland, is not a repeat of the same problem, it could still leave him on the sidelines and for United and Arsenal this tendency to be on the treatment table would be a worry.
Arsenal and United have both struggled to keep a consistent back-four because of fitness problems to a number of their first-choice players.
It has hurt their chances of meeting their expectations this campaign, with both looking to be particularly porous in defensive situations.
The two sides, who possess some of the best attacking players in England, have been shown up against higher level opponents and they know that drastic improvements need to be made in shutting out opposition teams.
It seems that Arsene Wenger and Louis van Gaal both are hoping to add quality in this area in January, but Vlaar is a player they should avoid, even if he is available at a bargain price.
