He rarely overlaps, Frank. Tell me, how often do you see in the modern game full-backs overlapping on the inside of the full-back when the winger is out wide? Quite often, right? Tony doesn't make those runs at all, and, he doesn't overlap on the outside on the right because there's rarely anyone to overlap on that side since no one has natural width. The pattern is set in stone. Tony is isolated on the right and he's faced with a choice; take on his man one-on-one or pass square of behind. Of course, we know that percentage wise he's going for option two 90% of the time. His isolation is tactical inasmuch as his lack of overlapping runs are tactical. Compare, for example, with Madrid, or even Arsenal (lack of success, granted); their full-backs how a very high field position when the team is in possession. Marcelo or Bellerin, for example, don't run into those high positions with the ball; they're already there by means of instruction. I'd grab screen grabs and do a visual comparison, if I had enough time, but it's difficult to explain in words only why people's perceptions of our lack of full-back activity is down to quality only. I want to say that it's not. What I can agree is that, of course, final delivery is purely down to Valencia, which he lacks, but what can be controlled is the effectiveness of his movement to offset his lack of ability one on one.
