Aye, Barca rated him highly - give it five years and we'll have them demanding for him to be let back home on a free
But going to nitpick a bit because of the perception that Rafa was anti-youth etc - Pacheco was eased into first team last season. General thought was that he had a bit more growing to do which is why he wasn't thrown in as much earlier and I think Rafa held back on using him as much as he may have done last season because of how poorly the team was playing (Souness did the same with Fowler - Evans reaped the benefits). Look at some of the young lads who are now blooded at first team level and are now being touted as being able to step up. Kenny reckons that's there 2 or 3 first team players of quality amongst just those - let alone those who have recently been brought in (Shelvey and Wilson) or those who are a bit further back (Palsson and the like). Rafa's left a gold mine there providing the club don't use it as a quick way to bring in money beyond selling at a profit those who clearly aren't going to make it.
And so I'm not off topic totally - looking like Insua to Fiorentina may be called off due to them not being able to offer him adequate personal terms and guarantees.
