Because then your best prospects piss off to Italy and you have to pay £100m to get them back.He was considered a midfielder then who could play full back (although he didn't until he joined Hull).

At 20, he was older than Pogba and already an international, so perhaps more likely to be brought back into the squad and considered before him.
SAF decided to chose experienced first team players. Why shouldn't he?
Rafael out of position isn't the best solution though, is it? Pogba didn't even get time from the bench.Had you seen him in any of the 7 games he got time in you would know he was far from ready for first team football. The PL was far to fast for him at the time, he looked like what he was, a little boy in the men's league.
