I do think that we've a had a problem defending set pieces this season, but I believe it is something that can be sorted out easily by AVB. Bossingwa, more often than not, the guilty party in my opinion should not be on the far post but maybe the first defender (instead of miereles in the pic) because of his weak abilities in the air. Coupled with some better man-to-man marking, I think our defense will be fine this season.
