Sánchez is a very talented player, excelent pass, great vision of positional game. He likes dynamic play, so you are going to see him pivot, and throwing flat passes. I think he is capable of make their back line play very fluidly.
He got a really brilliant foot also, maybe not to strong for long goal kicking but very precise, so in territorial kicking too. Defensively, he got an effective tackle, and I think is one of his keys. My concern goes trough his size, cause he is not that heavy, and didn't reach 1,80 meters, he played last two Vodacom Cup, so is used to play against big southafricans guys.
Hopefully the context wont be a struggle and affect him, and we' ll see him play at his best.
