Agree, I don't think its just injuries, we've been leaking goals and a little profligate as of late anyway. The midfield didn't help but we lacked killer instinct and gave up some silly goals, as one of the Spurs fans said earlier, another day despite the weakened team we're winning that game handy enough.
Whats worrying is we dominated Chelsea first half and lost (though completely outplayed second half) and dominated Palace and lost. We're losing games we should be putting to bed, Liverpool are doing the opposite, games where they should be dropping points they are finding a way whether by skill or luck. Thats what champions do, think of the number of games last season where Sterling deflected, shanked or scuffed a winner for us when the points didn't look likely, they were the games that put us miles ahead.
We really need KDB if we don't have Merlin, we can manage without one but not without both it seems. Essentially we played Palace without our entire first choice midfield, first choice striker, left back and had one of our first choice CB's out of position but in the end it was just one of those days.
