Arsene Wenger has suggested that Arsenal's injury problems have been made worse by some of his players taking medication without telling the club.
The Arsenal manager says that some of his injured stars may have hampered their recovery from injuries by taking certain supplements that have detrimental effects on vital organs.
The Gunners have been hampered by a number of injuries this season and the identity of the players in question were not revealed by Wenger.
Referring to the injury problems, he said told reporters: "Some of them are down to the medication that the players take that you don't even know about.
"Then you realise afterwards that they took this medication but that it's not prudent. For example, if you lose your hair and you've taken something to make your hair grow, it might not be good for the rest of your body. Medication always pushes a certain part of the body and is sometimes detrimental to other areas.
"I am surrounded by people who want to enhance their performance because they have another problem in their life and it's not always necessarily a good thing to do.
"The liver does not work so well, the toxins don't leave the body as quickly as they should and the player gets tired. At the moment we have not come to any conclusion.
"Every case can be different and you need to analyse very deeply why things happen."
The likes of Lukas Podolski, Alex Oxlade-Chamberlain and Santi Cazorla have all missed large chunks of the season through injury while Aaron Ramsey, Mesut Ozil, Jack Wilshere, Abou Diaby, Laurent Koscielny and Abou Diaby currently fill a packed treatment room.
The three month absence of Aaron Ramsey has hit Arsenal hardest as the midfielder was, without doubt, their standout player in the first half of the season. He has struggled to recover from a niggling thigh injury but returns to the squad for Sunday's game against Everton.
Wenger has since asked Arsenal's medical staff to investigate into why the injuries have been so bad at the Emirates this season.
