Doesn't seem too bad...
The last sentence sounds very bad because he's just saying that it
looks to be short-term. It wasn't supposed to be long-term when it happened on boxing day but he's been out for 3 months anyway. Now he's had yet another setback it seems.
Sorry, but that sounds very bad. He could just as well be out for the season but could also be back for next game. None of the alternatives would surprise me. Similar incidents always seem to happen at Arsenal.
Wilshere picked up an injury that was supposed to keep him out for a week. That changed to 3 weeks. It later changed to 2-3 months, then 5 months and in the end he was out for 14 months...
Not that those two injuries are comparable but there's obviously something wrong with either the training methods or the medical team. Completely ruining the potential of the team.
