Manchester United No2 Mike Phelan says their preseason injuries aren't a major concern.
Chris Smalling and Phil Jones have both broken down in recent weeks.
Phelan remarked: "As a club, you look at the issues that may have caused injuries. Some of those are created on the pitch and there's not a lot you can do about that. Maybe some have crept in through overuse or overwork but we've analysed those things and we're sure our players are prepared for what's always a hard league.
"All of these players are preparing for what could be a season of 60-plus games. That takes time, obviously. What we try and get to is a point where everybody is fit for selection in the first game of the season."
