I tend to use the Tokens I buy to get Green Packs so I can Hard Train the Cheap or Free players I pick up from the TM or the academy players I get once a season.
I very rarely use Red Packs (I have 50+ at the moment) to repair injured players, I just let them heal over the time set, but as I said previously I don't get many injuries and have not in the 4 seasons I've been playing the game.
Be rest assured, I've done plenty of reading on the forum and seen the numerous threads about injury levels, and yes I would be well hacked off if I had the levels of injuries that some seem to get, I'm just wondering though if there is another reason why some get more injuries than others, I can't believe that Nord would pick on certain users but not others (I don't think the engine is that good).
As for results, I've got a strong team for my league, but was knocked out of the cup in the first round by a team 2 leagues above mine and whilst I expect to progress to the next stage of the champions league, I'm sure I'll encounter teams that are a match for mine and won't win every match, but for me that's part of the game and I'll need to change my tactics and formations to cope with the way other teams are set out and play.
I'm also sure that I'll come up against weaker teams than mine and may suffer losses, but that's part of football.
