He has been great since called upon and it's an odd one too. Arsenal over the past year and a half have been pursuing, via the run of the rumour mill, young LB talents. I wonder if there was a personal intention to leave from Gibbs' perspective and Arsenal were trying to find cover if the inevitable did happen. Monreal is only getting older.
Aside from all of that, it's a toss up over who starts at LB right now, more evidence that the squad is being put to good use!
