I do mate. I watch us a lot, at every level.
I'm obviously exaggerating a little by saying Zabaleta was 'shit' last year, but he was certainly no better than Sagna, if not a little worse. We all (rightly) love Zaba, so I think we were easy to dismiss his efforts last season. He was bang average to poor. Slow, out of position, easily beaten. He looked fucked. There was no way he outperformed Sagna. My point is, if we're willing to give Zaba a year off, then we should excuse Sagna too who had the horrendously difficult task of rarely playing to get any consistency. Plus he played in a terrible backline as well.
Both are very, very good. Both should be considered equals as they go for the shirt this year. That is genuinely all I was saying :)
Edit - back on topic. De Bruyne is good.
