I think we can talk as much as we want about what players we'd like to bring in. But we need a manager who can actually outfox other managers. It seems that almost all season, managers have easily outsmarted Warburton.
We're always unlucky with injuries. But I take that as QPR usually being unprepared, which we've done for many seasons, regardless of which manager we have. That would suggest something is wrong at the club with regards to filling positions adequately, with backup players in stock.
But I do believe that a high quality manager could get some good football out of our squad. And we all can feel that Warburton doesn't seem to adapt mid game at all. We tend to basically play the same all game through, and when other teams adapt to us, we struggle.
Of course, going on a shopping spree for top players would make a difference. Which is why Harry Redknapp got results out of us: he had good players, which brought results even though his tactics were "go out there lads and enjoy yourselves."
