I'm pretty concerned at how we have capitulated since the derby.
Managers earn their corn in ensuring their team bounces back quickly. We've completely fallen apart. The players can't be trusted either to be fair. They will be loving the fact they can blame it all on that one moment.
I am fully of the belief that Silva thought that the squad - heck, the club, the fans included - would have the balls to come back from it, mate.
I think the Newcastle game genuinely was 'one of them'. He had to make changes because of iffy form from Walcott (which has carried on) and general fatigue. In that game we looked like a team that had given their all three days' prior and it showed.
Watford, for me, was where the old issues came back (conceding twice in a few minutes purely through defensive lapses, for example), and then City/Spurs probably knocked the stuffing out of the players because they were the first games we'd played against 'big 6' where we couldn't at least say we matched the teams for large parts, whereas I think the Arsenal, Man U and Chelsea games if anything gave us more confidence because of the chances we created.
We respond well against Burnley and then fail to follow it up. It's now about getting back into a settled system, for Silva to stop chopping and changing once we're through this rough patch (where, and I know you don't buy it but actual science disagrees with you, players do need resting, but it isn't an excuse for bad displays) and hopefully into a good run.
