it definitely wasn't out but it's impossible to be sure unless you have a slow mo replay. it's about a 2" difference
Didn't look like the ball went fully out, but that's about as close as it gets. The linesman would have to have Terminator vision to get that right.
3 at the back or 4 for Arsenal? Ox at RW makes more sense in a 4-2-3-1 than playing him at LWB. I guess we will know soon enough. I've seen both speculated on twitter
You think it's 3 at the back? The more I think about it the more that makes sense. Who played LWB when Monreal played at LCB last time?
