What we've seen an increased emphasis on forward passing from deep, and a continuation of a disordered front four. These are core essentials to Poch's systems in the past, and from what we've seen I expect them to be continued. I've actually been rather impressed with how Lennon's adapted in, as his performances as an inverted winger in the past have just been shockingly poor. But he seems to be enjoying contributing to the very different and intriguing style Poch's system creates offensively.
Especially given the interest in J Rod, I think it much more likely we see either Lennon in the role to continue Poch's plans or another left winger brought in, rather than Holtby or Eriksen playing wide. Certainly think that would have been tried out by now in the friendlies were it to be under consideration.
