I think this window has just exposed how cowardly Jose is/has become as a manager. It's not a huge shock, he was never a risk taker and it's very common for successful managers to become more negative as they get older.
Perhaps a harsh appraisal but ultimately he's had huge resources and an obvious problem: the squad doesn't score enough goals. So why has he failed to bring in players to address this? Looking at the ones we are linked with and looking at who he's used from the existing squad gives us our answer. He wants a Sanchez, someone whose defensively sound but also a phenomenal attacker. The problem is, he's a one off. Still, this is what he wants and this is why he targeted perisic.
It's very frustrating, we once again go into a season with red flags immediately present.
