I would much prefer if Jack stayed especially with our injury record.

Based on Saturday's lineup you would say that Cazorla is first choice and would be partnered with a more defensive minded player (Xhaka, Coquelin or Elneny). That leaves Jack and Ramsey to fight it out as the other CM. I can't imagine Cazorla playing every game and with Ramsey's injury record, I can see Jack getting plenty of minutes. Maybe Wenger has different ideas about the midfield combination though.
