Probably we get more money if they achieve wished results. It says up to 2M, so it depends if they qualify for EL or CL. I guess qualifying for CL gives us the full 2M, EL givey you 1M, and not qualifying gives you nothing (for example)
Basically: 2M for a 2 year loan
Another 0-2M depending on how their results are in those 2 seasons
16M option to buy
Edit: sporting objectives, it indicates its team achievements
