Journalist Alonso Rivero reveals that Tottenham have received an initial €5m (£4.2m) from Real Betis for Giovani Lo Celso but they will be owed more each time Real Betis qualify for the Champions League over the next four years.
Lo Celso completed a deadline day return to Betis, which did not come as a surprise, but it is unclear how much fee Spurs got for the midfielder, with various numbers being suggested by different outlets.
Rivero has now explained that the deal is a complicated one, with the Spanish club paying just an initial fee of £4.2m for the Argentine international.
However, there were some potential add-ons included in the deal that took Lo Celso from Spurs to Spain.
