Monreal looked great... early days; has pedigree, time, touch, though no right foot shot it seems (lol)... it sucks to be Gibbsy right about now unfortunately.
I don't think so, Gibbs is the incumbent for me, and a run of games from Monreal doesn't mean he'll dislodge him. Wenger is back to having a good selection battle at LB, and I don't think either one (baring injuries) will find themselves as the regular starter. Also having someone solid alongside Gibbs should see a reduction in injuries as they get rotated more.
