SAF said that he's going on loan and honestly...it makes sense. With Evra growing old we would soon need someone to cover/compete with him for a first team place. Fabio cant do that by simply play football at reserves level. He will also have to prove that he's not a sick note.
If he is being loaned out it means we have another Left Back coming in, otherwise one season long injury to Evra and we are screwed. If we have another Left Back coming in Fabio's future doesn't look as rosy.
Needless to say this isn't sitting pretty with me. Personally I would rather Evra play 50% of the matches he is and give Fabio game time, but if Sir Alex thinks Fabio some time away from his brother so be it.
