Even though Gabriel has only just returned to training, I do wonder if Arsène will take a gamble on him. Mertesacker has done excellently in recent matches, especially at Old Trafford but this is a very different game, a game that does not particularly suit him. As I mentioned above, we need to take the game to Monaco from the off, we need to compress them in their own half. Having Mertesacker half way in our own half does not help him or the team. For this same reason I wouldn't be surprised to see Gibbs come in for Monreal, although I think that is less likely as the form of the Spaniard has been top class for a number of months now
