Robin van Persie fears he may suffer long-term damage if he continues to play through the pain barrier, reports The Times.
The Manchester United striker has been receiving pain reliving injuries for a longstanding toe injury and is also suffering from a sore groin and calves.
The Times is reporting that Van Persie is happy to continue taking the injections but remains concerned that he is putting his long-term fitness at risk by doing so.
David Moyes is hoping to keep Van Persie in one piece until the international break, which comes shortly after Arsenal visit Old Trafford on November 10th.
Van Persie famously struggled with injury during his time with the Gunners and only reached his potential after overcoming the issues.
Not since 2011 has Van Persie missed a Premier League game, but it now seems the strain of playing week-in, week-out is beginning to take its toll.
Van Persie missed Manchester United's Champions League win against Real Sociedad on Tuesday but did start the following Saturday in the game against Stoke.
Whether the injections a good idea or not will throw fuel on the fire that there is an ongoing rift between Moyes and Van Persie at Old Trafford - a rumour denied by Moyes earlier this year.
