And we don't already have that coming through the ranks?
IMO, we don't - not of sufficient quality anyway.
We have Valencia and Nani as first choice wingers.
After that we have Park and Giggs. Giggs is getting on and we really need to look at replacing him (no matter how good he
can be). Park is an ok backup, but I really don't rate him as a winger.
After those, you have to look at Bebe, Obertan and Cleverly.
Bebe is still way off being good enough, and may never be - Fergie has also spoken of him as a striker too, recently, so we don't know if he will even be a winger if he does make it.
Obertan shows flashes, but no consistency. Not a first team player at this stag and another Fergie has spoken about in terms of being a central player, not a winger.
Cleverly has done quite well on loan, but (and this could just be me) I don't see him making it as a top winger - he doesn't have the skills of pace for it, more likely to eventually be an AM, a bit like Lampard imo.
In terms of wingers coming through the ranks, we are a bit thin imo - to the point where we are playing Josh King (imo, very much a striker and the potential to be a very good one) on the wing as we don't have other options at Reserve level (and Obertan is played through the middle). Robbie Brady is another youth option, but I honestly don't see enough in him to be a viable long term option.
I suppose you would have to include Fabio, and maybe he will be a winger for us - I can't say to be honest - but right now I would still peg him as a fullback.
So, the way I see it - we definitely have room at the club for another winger in the first team picture, I don't rate a good number of the 'options' we currently have.
