Arsenal manager Arsene Wenger insists the club will "follow our own recommendations" on how best to help Mesut Ozil recover from a knee injury.
The German Football Federation announced on Wednesday the midfielder was set to be out for "10 to 12 weeks" as scans from international duty revealed a "partial rupture of the outer band of the left knee joint" after Ozil had complained to Arsenal's medical staff of pain after Sunday's 2-0 defeat at Chelsea.
The Barclays Premier League club, however, later released their own statement insisting no time frame had yet been set for the recovery of their record signing, with a story on the club's official website on Thursday suggesting "Wenger knows he will be without the 25-year-old for at least two months".
Whatever the time frame, Wenger accepts he will have to be patient with Ozil's return to full match fitness, which could well not be until the start of 2015.
"When he arrived with the German national team, they didn't think it was a lot at the start. He was supposed to practice on Wednesday but, in the end, he said that wasn't possible for him," Wenger said on http://www.arsenal.com.
"Then he had a scan and it was bad news. We have our own specialist giving us his opinion after reading the scan and examining Mesut. We will follow our own recommendations."
Arsenal's injury problems continued when central defender Laurent Koscielny was released from international duty with France.
Press Association Sport understands Koscielny has a minor Achilles problem and the decision is precautionary, with the Gunners confident he will be fit for the Premier League clash at home to Hull a week on Saturday.
Les Bleus play Portugal on Saturday and Armenia next Tuesday in friendlies building up to their hosting of Euro 2016.
Arsenal, however, have been able to report some positive news, with Theo Walcott and Serge Gnabry back in full training following knee injuries, while midfielders Aaron Ramsey (hamstring) and Mikel Arteta (calf) are also continuing their rehabilitation on schedule.
Wenger added: "Theo is not too far away now. Serge has been out for a long, long time and Theo has also been out for nine months, so it's good to see them back. They've worked very hard and they're very dedicated. They are back in the group on a daily basis and that's very good news.
"For Ramsey it's day 13 today and I think it will be day 21 before he is back into training. Arteta may be back with the group late next week."
Arsenal's injury list
Arsenal's injury list
1/5 Mikel Arteta (midfield)
Like Diaby, the Spaniard is closing in on a return but the Swansea match will come to soon. The club captain last played in November.
2/5 Mathieu Debuchy (defender)
Returned in the FA Cup semi-final win over Reading but has since been ruled out with injury and Wenger confirmed he remains 'unavailable'.
3/5 Alex Oxlade-Chamberlain (midfield)
Suffered a hamstring injury against Manchester United in the FA Cup and hasn't played since as it has exacerbated a groin problem. Out at least until May and facing surgery in the summer.
4/5 Aaron Ramsey (midfield)
Aaron Ramsey caught a kick on his calf during the win over Hull and was later substituted. The Welshman was rated 50/50 for the Swansea match by Wenger, but it now appears that he is a major doubt for the clash at the Emirates.
5/5 Danny Welbeck (forward)
Danny Welbeck has not played since the goalless draw with Chelsea towards the end of April after suffering a knee injury. Wenger has confirmed that the injury is 'nothing major', and that he should return to full fitness before the end of the season.
Defender Mathieu Debuchy and Olivier Giroud, however, remain long-term absentees.
