Arsenal midfielder Tomas Rosicky could be facing another six weeks on the sideline as his painstaking return from injury continues.
Reports on Thursday morning suggest the Czech Republic international has pulled a hamstring in training and will now miss the first month of the season.
Rosicky has been battling to return to action after 18 months out but after his latest setback, he's been told by medical staff that he will be missing until mid-September.
Arsene Wenger will now be without the midfielder for up to four Premier League matches, and the club's Champions League qualifier.
Just last week Rosicky was bullish about Arsenal's chances of retaining the title. He said: "We have got plenty of options and that is why I feel we will be stronger than last season because the boss will have more options."
