The point is that is all pure speculation. Yes the manager is on his last legs and yes he has rushed players back, most notably Harry Maguire recently but the evidence isn't there for this one.You don't think it's connected. Player can't run due to groin injury for 3 weeks. Ole then plays him twice in 3 days, hence easy to pick up another injury
It does seem like Varane is injury prone as some had feared.
