Exactly mate. That's what I see every time I watch them play, they are so porous it's unreal.
Parker's tactical game is way below other similar players, I'm talking about the top boys here. He runs a lot, puts his body on the line for his team, but he doesn't have a good understanding of what's happening around about him. Some of that is down to the lack of coordiantion between the midfield and the centrebacks and the gaps that appear between the two lines, but Parker runs around pretty much clueless most of the time.
Whatever the case, Spurs are NOT a good team from a defensive point of view.
