While I know he has been training this season, didnt he take a complete break last season for the couple of months you previously mentioned (at the time I thought a club statement said he was, or had been, bed ridden) , if this is correct (and having little long-lasting effect) the time scale has to be much longer this time around , especially given that this time around the real reason has now been realised (so less pressure on everyone involved)
yes and no, a lot of the time with these things its stress that plays a huge factor. Think about if you were Fletcher, would there be any stage in which you took 2 months off, hoping to be back, you wouldn't be doing some exercise staying fit and essentially stressing yourself out for being unable to get better.
As someone who deals with a crapload of stress and knows other people who do also, one of the ridiculously stressful things in life, is stressing over being unable to stop being stressed
Basically Fletcher with the intention of wanting to come back, with premier league titles on the line while being paid millions, this isn't a stress free situation, that isn't to say some people wouldn't be able to get through it, nor that others would, these kinds of diseases hit everyone in various ways, short sharp bad bouts, long less bad bouts, and everything in between.
The best thing is probably not always trying to be a month away from a comeback, that is probably the worst situation for trying to get better, think of all the guys who get reinjured trying to come back from injury too soon, or just while pushing hard to get back.
HE's taking what you could somewhat describe as unofficial retirement, Fergie is officially telling him, you go, we're not relying on you, we don't have to have you back, if you ever get better, door's open, if not, so be it.
Let him as I said, unofficially retire, de-stress, if he gets better, he gets better, it could be in 2 months with all the stress off his back, it could be a couple years, or never.
