In terms of shot stopping, the fundamental skill of a keeper, it's about making the striker make a choice, putting doubt in his mind if you can, by staying non-committed as long as you can. De Gea showed this countless times today, Jones was beaten twice when he quite simply failed to do this, by putting himself in a poor position, making the strikers mind up, and effectively giving them an open goal. The rest of his game, I'd agree, was more impressive than Mignolet has been, for instance I liked how he was quick to distribute, rather than the hesitant Mig. However, if you can't at least put yourself in position to stop shots like those today, then you shouldn't be playing at all. Mig needs replacing, but he's a safer pair of hands than Jones, without question. Every team gives up goals, but it's unlikely we'd have conceded the first and third with those 3 you mentioned. Very unlikely.
