largely might just be a tiny bit of a stretch. he played like 15 minutes, and was unavailable for 4 of our 5 matches so far. true, he scored a brilliant winner in moscow, but where was he when the team collected 10 points of the remaining 4 matches?
without costa's last second winner, the group standings _could_ look like this:
juve 11
atleti 7
bayer 6
lokomotiv 4
looks like juve could have already won the group without his contribution.
