I had just 3 injuries until yesterday, all three of them with a length of 5 days. Unlike last season, this time it's only key players who are getting injured and I needed to heal them immediately, so red packs were used.

Then yesterday my first choice DR got injured for 6 days just 20 minutes short of my CL match.
20 minutes into the match itself my first choice DL got injured (4 days)
Then just after the second half started my AML/ML got injured (5 days).

How convenient ... my opponent was attacking through the flanks and so do I, only I don't have another left midfielder. Lost 0:2, out of the CL and 10+ green packs wasted due to matches again being too close - all in just 30 mins.
