A lot of problems with injuries can result from low condition, low match fitness and jadedness (which effects condition during matches). And luck.
If a manager (the manager being myself :-) and this is purely my opinion and experience that I've enjoyed) is firefighting injuries, this is what he would do -
- Make sure he has enough physios with good physio stats. If nothing else he has better estimates when players will be back and help manage the depth of the team for injured positions.
- Turn team training intensity to low or very low - this will limit jadedness increases (which effects condition during matches). Additionally there will be less injuries from training injuries due to low conditions.
- Consider resting players before a match to improve condition so they are less likely to get injured during the match.
- Consider resting players after a match to prevent injuries during training (the manager wouldn't do this if training is set to low or very low intensity - but might if there are a lot of injuries)
- Stamina effects condition, so consider changing general training to fitness for a chunk of the season for stamina gains.
- Stye of play effects condition. Flogging his players with super high tempo, closing opposition down, getting them stuck in against stronger more aggressive side will effect condition. Worth thinking about for those looming injuries.
- Ensures he has the best fitness staff.
- Plays players in under 21 teams till match fit for 45 minutes max.
- Doesn't always talk about himself in the third person.
