Manchester United manager Sir Alex Ferguson admits there is no time frame on the return of midfielder Darren Fletcher.
The Scottish international captain announced he'd be taking an indefinite break from football at the end of November, with a chronic inflammatory bowel condition cited as the reason behind the decision.
It was a problem which had plagued Fletcher's recent seasons at Old Trafford, impacting the amount of minutes he could play for the Red Devils. And the 70-year-old manager admits he is unsure when his compatriot will return to action for the champions.
"He's been coming into training for the last few days, just getting himself out of the house really. It is difficult to put a time on it because it is not one we can assess accurately," said Ferguson.
"It is what it is and hopefully time will be the answer."
United did have some positive injury news to reflect on today though, with talkSPORT reporting that Tom Cleverley will be back in training this week.
The young England international has been out of action since October, damaging ankle ligaments in the win at Everton after an impressive start to the campaign.
But, after working on his fitness at the club's gym and pool, the former Wigan loanee is poised to start running again at Carrington, and could be in contention at the start of February.
