Didn't he also apparently tell Courtois and Hazard in "how to beat us"?
Thing is, how many times last season (and arguably the last two matches ala Palace and Villarreal) did we see a cross whipped in with not one of our attackers making a run to the box? They are all either sitting outside the box or they instinctively made the wrong run.
We are always complaining on how we make the wrong decision in the build up in the final third, what if that is down to not having a focal point?
