Does a specific player has increased injury tendency?

... for long term he's rather underperforming (6-7-7-6-8-7).

I agree that this statistics are not very bad for a MC even for long term. In my experience, some MC performed very badly, say 5-5-5, on joining the team but would eventually develop to quite good players. As I remember, 2 such MC were used to be my all time best assisters (for 2 different teams) before overtaking by others later.

Hello folks,
One thing though worries me. He has been injured already 5 times during this season, even though I never train or put a player in a match if his condition is below 80%. In match I regularly swap exhausted guys around 70th minute. This guy has sucked most of my health packs...

I generally believed that some players are more injury prone, and have no idea if the best players are easily injured. But I cannot remember very well because i don't have obvious injury problem in these 2 seasons. Now I use very red packs very cautiously. Generally I don't use them on injuries with players out for less than 4 days unless there is no replacement for that player. Eventually, my accumulated red packs rises significantly.

Hello folks,
So I put him on market as soon as he got his sixth star.

If you want to sell him, he is more attractive before promoting to next star. But this may be less obvious if you are in low level.
