It might have but it would have taken a well timed run and pass. Valencia's failure to step out meant they had a huge margin for error on both elements. It was horrible defending all round, really. All the more frustrating because it involved four players usually known for their defensive smarts (Blind, Smalling, Schneiderlin and Darmian) If any of them had done their job a bit better then Valencia's naivety would have been much less of an issue (still an issue though)
The comment about "some people" wasn't aimed at you btw.
@Nobby style has been a fervent defender of Valencia for ages (sometimes with good reason, sometimes not so much) which seems to have translated into a desire to constantly belittle Valencia's replacement, Darmian. Who's had a couple of ropey displays but has generally been excellent (i.e. better than valencia)
