Task: Question Generation
Input (English): Passage: Considering revenue alone, Inter surpassed city rivals in Deloitte Football Money League for the first time, in the 2008–09 season, to rank in 9th place, one place behind Juventus in 8th place. (Milan in 10th place.) In the 2009–10 season, Inter remained in 9th place, surpassing Juventus (10th) but Milan re-took the leading role as the 7th. Inter became the 8th in 2010–11, but was still one place behind Milan. Since 2011, Inter fell to 11th in 2011–12, 15th in 2012–13 and 17th in 2013–14 season. In 2008–09 season, Revenue percentages were divided up between matchday (14%, €28.2 million), broadcasting (59%, €115.7 million, +7%, +€8 million) and commercial (27%, €52.6 million, +43%). Kit sponsors Nike and Pirelli contributed €18.1 million and €9.3 million respectively to commercial revenues, while broadcasting revenues were boosted €1.6 million (6%) by Champions League distribution. in 2009–10 season the revenue was boosted by the sales of Zlatan Ibrahimović, the Treble (association football) and the release clause of coach José Mourinho. For the 2010–11 season, Serie A clubs started negotiating club TV rights collectively rather than individually. This was predicted to result in lower broadcasting revenues for Inter, with smaller clubs gaining from the loss. Eventually the result included an extraordinary income of €13 million from RAI. Deloitte expressed the idea that issues in Italian football, particularly matchday revenue issues were holding Inter back compared to other European giants, and developing their own stadia would result in Serie A clubs being more competitive on the world stage.
Output (English): How many more million €s did Nike contribute to commercial revenues compared to Pirelli?
