Total probably
I suppose It'd be the latter. The former would hardly be realistic to achieve. He scored 6 goals last year.
I know he's not exactly a goalscorer and Dortmund also knows that. While his goalscoring record would probably improve with Messi creating chances for him 30 goals in a season is still a lot so I also suppose it's total goals. He would probably reach that mark in his 3rd or maybe at the end of 2nd season. So probably pretty easy attainable 20M for Dortmund but still better than just pay them upfront.
Source is @BilelAffelay, dunno if reliable.
The 30 goals would have to be in one season I think.
edit: during the whole contract indeed, not just 1 season. So pretty easily to achive.
Don't know the guy, we'll see if some more known/reliable journalist will give us more informations about that.
